回顾微软Surface Pro的平板电脑
For the original German review, see here.
The Microsoft Surface RT had a number of disadvantages regarding its relevance to the normal user. It was always going to be bogged down by incompatibilities with the existing software ecosystem developed around the X86 version of Windows 8. The Surface Pro is the device that is similar to the Windows RT tablet but uses the established Intel processor technology. The advantages are abundantly obvious: Windows compatible software and hardware can both be used without problems, in the same way as other Windows PCs, which circumvents the requirement for additional accessories or to wait for custom applications. Apart from this, the available hardware including everything from a hard drive to a shared printer or a DVB-T receiver can be used without any compatibility issues. This means that development and user costs are low for this device.
Right now, the Microsoft Surface Pro isn’t available in Germany and the website does not mention any date of availability. For the purposes of this review we used a US model with a storage capacity of 64 GB. The other option available for sale is the 128 GB version. We can only speculate on the price of the device when it is made available in Germany and we estimate it to be around the 800 Euros (~$1050) mark.
对于的德国原装审查，在这里看到。
微软Surface RT有一些缺点，就其正常用户的相关。它总是将要陷入了周围的X86版本的Windows8开发与现有的软件生态系统不兼容。表面Pro是类似的Windows RT平板，但使用已建立的英特尔处理器技术的设备。丰富的优点是显而易见的：Windows兼容的软件和硬件都可以使用没有问题，在以同样的方式与其他Windows电脑，规避该要求额外的配件或自定义应用程序等待。除此之外，可用于包括一切从硬盘驱动器的共享打印机或DVB-T接收可用的硬件没有任何的兼容性问题。这意味着该装置的开发和用户的成本是低的。
眼下，微软Surface Pro的是没有在德国和网站没有提到任何的可用性日期。对于这篇评论的目的，我们使用的是美国模式，存储容量为64 GB。其他选项可供出售的是128 GB的版本。我们只能推测该设备的价格上，它是由在德国，我们估计大约为800欧元（〜$1050）标记。
Case
The device is mostly edges and sharp corners that make it stand-out among other devices with the same form-factor. The magnesium alloy case is well made and the individual elements have been assembled with precision. The rigidity of the case is very good, and can be directly compared to that of the iPad. The kickstand integrated into the back which allows the device to be propped up, proves itself to be very practical; although we need to point out that there is only one position possible.
The powerful hardware components and the material of construction contributed to the weight of the device which came out to be about 920 grams. This may be light enough for comfortable transportation in a sleeve or in a bag, but not for holding in one hand for anything longer than a few minutes. Our comparison device, the iPad 3 is almost 300 grams lighter at 650 grams, making it much more comfortable to hold in one hand. We expected the thickness of the device to negatively impact the user experience but we found it to be a decent form-factor to hold making it comfortable to use with one hand for at least short periods.
该设备大多是边缘和尖角，使其站在了相同的外形与其他设备之间。镁合金外壳，制作精良，已装配精度的各个元素。刚性的情况下是很不错的，可以直接的iPad相比。支架集成到后面它允许设备撑起，证明自己是非常实用的，虽然我们需要指出的是，有可能只有一个位置。
强大的硬件组件和施工材料贡献出来的装置，约920克的重量。这可能是光照充足，舒适的交通运输在套筒或在一个袋子中，但不适用于持有在一方面为任何超过几分钟。我们的比较器，iPad 3的轻了将近300克，650克，使得它更舒适，一方面举行。我们预计设备的厚度为用户体验造成负面影响，但我们发现它是一个体面的形式持有的因素使得它舒适的单手使用，至少短时间。
Connectivity
eshiqingTo make the device appeal to businesses, Microsoft has included the mini-Display port and the mini-HDMI port for external display connections. We were not able to check if the ports were able to output a higher resolution than 1080p as we did not have the appropriate monitor at the time of writing this review. The device does not include a Thunderbolt port. The USB port present was the faster USB 3.0 version which allowed us reach read speeds of 238 MB/s using a solid state external hard drive.
Under the Windows logo, there is a form of docking port that allows for the integration of an external keyboard if necessary. There are no other ports on the device. On the right side of the tablet, there is a somewhat smaller, but otherwise identical type of connector, which is intended for the power supply or the input pen. The power supply also has an integrated USB port (5 watts) for charging external devices such as smartphones and MP3 players.
eshiqingTo使设备企业的吸引力，微软已经包括迷你显示端口和迷你HDMI端口，外接显示器连接。我们不能够检查如果端口能够输出分辨率高于1080，因为我们没有在写这篇评论的时候有合适的显示器。该设备不包括Thunderbolt端口。 USB端口，目前需要的是更快的USB3.0版本，这允许我们达到238 MB / s的读取速度，使用固态外部硬盘驱动器。
在WINDOWS下进行标识，还有一种形式的底座端口，允许外部键盘如果必要的整合。有没有其他的设备上的端口。在右边的片剂，小一些，但在其他相同类型的连接器，其目的是为电源或输入笔。该电源还具有集成的USB端口充电的外部设备，如智能手机和MP3播放器（5瓦）。
Communication
Microsoft has incorporated a rare WLAN module from Marvell that features two antennae and is able to work on both the 2.4 GHz and the 5 GHz bands. This type of module is not normally seen on Intel based devices. In addition to this, the chip already supports the WLAN standard 802.11ac, and can theoretically transfer data at a rate of 867 Mbit/s. During practical use we were able to observe a good signal strength which didn't show any unusual behavior. Also integrated into the module are Bluetooth 4.0 and NFC chips. The two webcams both have a resolution of 1280 x 720 pixels, which should be sufficient for taking pictures of auction items or for video telephony with limited quality demands, but doesn't reach the quality provided by iPad & company to a large extent. A version of the Microsoft Surface Pro with a WWAN module is so far not on the horizon. In this case, users will have to rely on external devices such as a USB stick, WLAN router or tethering via a smartphone.
Maintenance
The case is not intended to be opened by the end users. The battery and all the other components are integrated and should only be changed by authorized service partners.
Warranty
Microsoft grants a manufacturer’s warranty of 2 years. Extensions to the warranty haven't been found by us so far, but could almost certainly be determined once the Surface Pro is available in Germany.
沟通
微软已经成立了一个难得的WLAN模块来自Marvell，设有两个天线能够同时在2.4 GHz和5 GHz频段工作。这种类型的模块，通常不会看到基于英特尔设备。除了这个，该芯片已经支持WLAN标准802.11ac标准，理论上可以的867 Mbit / s的速率传输数据的。在实际的使用过程中，我们能够观察到良好的信号强度，并无发现任何不寻常的行为。此外，集成到模块蓝牙4.0和NFC芯片。这两个摄像头的分辨率为1280×720像素，采取拍卖的物品的照片或视频电话与有限的质量要求，这应该是足够的，但没有达到在很大程度上提供iPad及公司的质量。微软Surface Pro与WWAN模块的版本是到目前为止还没有在地平线上。在这种情况下，用户将不得不依赖于外部设备，如USB记忆棒，无线路由器或圈养通过智能手机。
保养
的情况下，不适合在最终用户打开。电池和所有其他组件集成，只应更改授权服务伙伴。
保
微软授予制造商的保修期为2年。保修的扩展没有被我们发现，到目前为止，但几乎可以肯定地确定一旦表面Pro是在德国的。
Input Devices
Touchscreen
The high resolution of the display provides the opportunity to display a larger amount of data compared to the iPad 3 and 4. From a user perspective this does however make the icons and symbols too small for reliable touch control away from the desktop; something which should be better with the input pen that would normally be included, but wasn't in the case of our private review sample. Alternatively, an increase of the icon size to 125 or 150 percent should ameliorate this issue. The adjustment is well supported by most applications, and provides for legible icons and menu options. The sharpness isn't quite as good as on the iPad though, and looks a little blurred. Otherwise, the display responds well to touch commands, has good gliding characteristics, and supports the usual multi-touch gestures such as zooming and turning.
On-Screen Keyboard
The display keyboard only has a curtailed selection of keys in its standard configuration, although this should still be enough for many tasks and also provides for relatively large key sizes. The keyboard can also be split into several parts, the size can be changed and it can also be moved. Additional keyboard layouts, including a complete set of keys can of course be selected depending on the requirements.
触摸屏
高分辨率显示屏提供了机会，以显示更大的数据量相比的iPad3和4。从用户的角度来看，这不过太小了可靠的触摸控制的图标和符号远离桌面，这应该是更好地与输入笔，通常会被列入的东西，但不是在我们的私人审查样本的情况下。另外，图标的大小，125％或150％的同比增长应该改善这个问题。调整支持大多数应用，提供清晰的图标和菜单选项。虽然在iPad上的清晰度是不太好，看起来有点模糊。否则，显示响应触摸命令，具有良好的滑动特性，并支持常见的多点触摸手势，如缩放和转动。
屏幕上的键盘
仅显示键盘键在其标准配置有缩减的选择，虽然这仍然是不够的许多任务，也提供了比较大的密钥大小。的键盘，也可以分割成几个部分，大小可以改变，它也可以被移动。其他键盘布局，包括一组完整的键当然也可以根据需要选择。
Our test model was provided with one of the two attachable keyboards. The Touch Cover (120 Euros/~$160) is a 3 mm thick plastic lid with a matte surface which reacts to touch input without any key movement. It is especially thin and light, and also serves as a protective layer for the display. After a short period of acclimatization to the Touch Cover we were able to work with it quite well. Instead of the haptic feedback you get with other keyboards, there is an acoustic confirmation via the speakers which lets you know whether the key press was successful or not. This may take some time to become accustomed to, but doesn't get annoying. The integrated Touchpad is very small and actually quite superfluous, since touch control on the display is considerably faster and easier. The Touch Cover increases the weight of the Surface Pro by 210 grams. Additional impressions can be found in the review of the Microsoft Surface RT.
An alternative provided by Microsoft is the Type Cover, which is endowed with real keys. This weighs approximately 50 grams, consists of hard plastic and costs 130 Euros (~$170). With a depth of 6 mm, it is somewhat thicker, but provides the conventional key feedback. Unfortunately, we weren't able to test the Type Cover for this review.
The input pen which is normally included with the standard delivery, attaches to the magnetic power input, and can therefore be attached to the case only when the power supply is not connected. Using a safety cord for the pen, as is often customary with business convertibles is not an option. The input pen supports the input determined by varying amounts of pressure, although this is not recognized by all the applications. The pen was not compatible with Photoshop CS6 but we found it to work with programs like SketchBook Pro 6 and Art Rage 4. The stylus is not compatible with either the Dell Latitude XT3 not the HP Elitebook 2760p.
我们的测试模式提供了与两个附接键盘。触摸盖（120欧元/〜$160）是一个3毫米厚的塑料盖采用了磨砂表面没有任何按键动作对触摸输入反应。这是特别薄，轻，并且也可作为用于显示的保护层。经过短短水土不服触摸盖，我们能与它的工作相当不错。取而代之的是你与其他键盘的触觉反馈，有声通过扬声器让你知道按键是否成功与否的确认。这可能需要一些时间去习惯，但没有得到烦人。集成触摸板是非常小的，其实挺多余的，因为在显示屏上的触摸控制是相当快，更容易。触摸盖增加了210克的重量，表面临。额外的展示，可以发现在审查微软Surface RT。
由Microsoft提供的另一种类型的封面，它被赋予了真正的关键。重约50克，由硬质塑料，费用为130欧元（约$170）。的深度为6毫米，稍厚，但提供的常规的重要反馈。不幸的是，我们无法测试类型盖评语。
通常是附带的标准发送的输入笔，磁动力输入的重视，并因此可以被连接的情况下，只有当电源未连接。使用安全绳笔，往往与业务敞篷习惯是不是一种选择。输入笔支持的输入确定的不同量的压力，虽然这不是确认的所有应用程序。笔用Photoshop CS6不兼容，但我们发现它的工作程序，如速写本Pro6和艺术怒气4。笔是不兼容的戴尔Latitude XT3惠普EliteBook2760P。
Display
The glossy 10.6-inch display has a resolution of 1920 x 1080 pixels meaning a pixel density of 207 dpi. This is very high and can lead to very small letters and symbols on the tiny display. The presentation is very sharp when using the native resolution, but long-term use could cause some users discomfort due to the strain on the eyes. The scaling can be changed in the appropriate options section but please do keep in mind that the change can lead to a loss in sharpness when higher font sizes are chosen.
光滑的10.6英寸显示屏，分辨率为1920 x 1080像素即像素密度为207 dpi。这是非常高的，并且可以导致非常小的小显示屏上的字母和符号。这次报告会是非常尖锐时使用的原始分辨率，但长期使用可能会导致一些用户对眼睛的应变引起的不适。缩放可以在适当的选项部分改变，但请记住，这一变化导致的损失清晰度更高的字体大小选择。
The brightness of the Samsung panel was measured at nine different places on the display. The lower left corner is the darkest with a brightness of 337 cd/m², while the brightest area is at the center of the screen with a read of 371 cd/m². The varying levels of brightness cannot be recognized even with monochrome images. On average, the display reaches a maximum of 355 cd/m² while the illumination distribution lay at 91 percent. Since brightness can only be adjusted with a sliding controller, it is difficult to set a precise value. When the controller is set at about one third the brightness we measured was about 151 cd/m²- would suffice for use indoors with a matte display in most cases. In order to trump the reflections however, users will often have to set the brightness to a higher level.
三星面板的亮度测量显示屏上的9个不同的地方。左下角是最暗的亮度为337坎德拉/平方米，而最亮的区域是在屏幕的中心与一读为371坎德拉/平方米。不同级别的亮度不能被确认，即使与单色图像。平均来说，显示达到最大为355坎德拉/平方米的照度分布，而在于在91％。由于亮度只能调节滑动控制器，它是很难设置一个精确的值。当控制器设置在三分之一左右，我们测量的亮度约为151坎德拉/平方米 - 就足以在大多数情况下，采用了磨砂显示用于室内。为了王牌反射然而，用户往往会产生，设置亮度到一个更高的水平。

Outdoor users will have to be content with limited visibility of the contents in the same way as with most other tablets. The brighter the surroundings, the darker the display of the tablet, the more pronounced the effect. At least the maximum brightness of 371 cd/m² - is also available on battery power, and this is able to counteract the loss of legibility of the screen content to a certain extent.
The contrast ratio of 741:1 is significantly less than that of the Microsoft Surface RT (1079:1) which we have reviewed, but only marginally less than that of the iPad 4 (838:1). For practical purposes, the display has a very good level of contrast that differences can only be discerned with a direct comparison with other devices. Saturated colors and relatively deep blacks mean good presentation of pictures, videos and games. The covered color space is relatively small and doesn't even begin to approach the sRGB color space. While the greyscale presentation and color saturation can be improved with some calibration, this is only possible to a minimal extent in the case of the color accuracy due to the curtailed color space.

741:1的对比度显着小于微软Surface RT（1079:1）我们已评论，但仅略小于的iPad4（838:1）。为了实用的目的，显示有一个很好的对比度水平的差异仅可与其他设备的直接比较中看出。色彩饱和度和相对深黑色的意思是良好的演示图片，视频和游戏。覆盖的色彩空间相对较小，甚至没有开始接近sRGB色彩空间。虽然灰度和色彩饱和度和可改善与一些校准，这是唯一可能由于缩减的颜色空间的颜色精确度的情况下，到最小的程度。
The IPS panel provides for very wide viewing angles and a very even representation of the display contents. Depending on the viewing position, users may however have to come to terms with slight discolorations and varying levels of brightness. Altogether, the display in the Microsoft Surface Pro is on the same level as the (consumer) competition, and doesn't exhibit any glaring shortcomings. Due to certain specific requirements, some business users could however end up being disappointed with the display. The only added value when compared to many other alternatives is merely the high resolution which allows for more productivity. The color space, contrast level, brightness and the glossy surface of the display are all characteristics that could be improved or changed depending on the parameter to better cater to the specific business user set.
IPS面板提供了很宽的视角和非常均匀的表示形式的显示内容。根据观看位置的不同，但是，用户可能有轻微的色斑和不同级别的亮度来。总而言之，微软Surface Pro的显示是在同一水平上竞争（消费者），并没有表现出任何明显的缺点。一些企业用户可能由于某些特定的要求，但最终被失望与显示。时相比，许多其他的替代品的附加值仅仅是分辨率高，这使得更多的生产力。色彩空间，对比度水平，亮度和光滑的表面显示可以改进或改变参数，以更好地满足特定的业务用户组的所有特性。
Performance
The Microsoft Surface Pro comes with hardware components usually found in Ultrabooks. An Intel Core i5-3317U CPU with integrated Intel HD Graphics 4000 graphics, 4 GB of RAM and a fast storage device with a capacity of 64 GB promise a chart-topping performance. As an alternative, Microsoft should also provide a 128GB SSD version of the Surface Pro when it becomes available in Germany.
微软Surface Pro配备通常在超极本的硬件组件。英特尔酷睿i5-3317U处理器，集成Intel HD Graphics4000显卡，4 GB的RAM和一个快速的存储设备容量为64 GB承诺高居榜首性能。作为替代方案，微软也应该提供一个表面PRO128GB SSD版本，当它成为在德国。
Processor
The Intel Core i5-3317U CPU is an ultra-low-voltage processor, which is geared towards low power consumption. The thermal design power (TDP) lies at 17 watts, and is reached by using relatively low clock speeds between 1.7 and 2.6 GHz. The technologies Turbo Boost and Hyper-Threading are both supported, and guarantee an optimized processing performance. With single-core applications, the maximum clock speeds can be reached, while the CPU is able to process up to four threads simultaneously with multi-thread applications.
When it comes to pure CPU benchmarks, the results were in line with our expectations and identical to those achieved by Ultrabooks using similar components. Cinebench R11.5 (64-bit), for example, ascribed scores of 0.9 (single-thread) and 2.39 (multi-thread) points. The Super Pi 32M calculation (single-thread) took 727 seconds, while the wPrime 1024M calculation (multi-thread) required 653 seconds. Altogether, the results lie in the upper range of comparable Intel Core i5-3317U values.
We tested the processing power by converting three MP3 files into the AAC format with iTunes. The pure CPU conversion of videos with MediaEspresso took considerably longer than other devices and probably isn't a task that should be performed by a business tablet all too often. Things move noticeably faster with Intel's Quick Sync technology which, by the way, also requires significantly less processing power (about 20 percent instead of 90 percent).
During maximum utilization of the CPU and GPU (Prime95 and Furmark), we witnessed an obvious reduction of the clock speed from 2.4 GHz to 1.2 GHz within a few minutes. During pure CPU utilization, the tool HWinfo showed minimum throttling from 2.4 GHz to 2.3 GHz. Both of these didn't have any discernible effect on the benchmark results or cause any slowdowns in the running of the tablet.
While battery powered, we weren't able to notice any additional performance impediments other than those described above. Exactly the same result of 2.39 points was achieved with the Cinebench R11.5 (multi, 64-bit) benchmark.
英特尔酷睿i5-3317U处理器是超低电压处理器，这是面向低功耗。热设计功耗（TDP）是17瓦，达到使用相对较低的时钟速度1.7 GHz和2.6 GHz之间。技术睿频加速和超线程支持，并保证优化处理性能。与单核心的应用程序，最大时钟速度可以达到，而CPU能够同时处理四个线程与多线程应用程序。
当它涉及到纯CPU基准测试，结果符合我们的预期，使用类似组件的超极本实现相同。的Cinebench R11.5（64位），例如，赋予分数0.9（单线程的）和2.39（多线程）点。与Super Pi 32M计算（单线程）花了727秒，而需要跑wPrime 1024M计算（多线程）653秒。总而言之，结果趴在可比的英特尔酷睿i5-3317U值的上限范围。
我们测试了三个MP3文件转换成AAC格式与iTunes的处理能力。纯CPU转换视频MediaEspresso比其他设备花了相当长的时间，可能不是一个应该执行的任务往往由商务平板。事情明显移动速度与英特尔的快速同步技术，顺便说一下，还需要显着较少的处理能力（约20％而不是90％）。
过程中最大限度地利用CPU和GPU（Prime95的和的Furmark），我们看到在几分钟内从2.4千兆赫至1.2千兆赫的时钟速度的明显降低。在纯CPU利用率，工具另外HWiNFO表现出最低的节流从2.4 GHz到2.3 GHz。这两者并没有任何明显的效果的基准测试结果，或造成任何的平板在运行速度变慢。
电池供电，虽然我们没能发现任何上述以外的额外的性能障碍。完全相同的结果2.39点多，64位的Cinebench R11.5（）基准。
System Performance
With PC Mark 7, the Microsoft Surface Pro achieves an identical result as the Dell XPS 13 and the Acer Aspire S7-191 with 4813 points. A large portion of this can be attributed to the dualchannel mode of the RAM modules and the superfast solid state drive. The only improvements that can be done would be the upgrade to a better CPU-GPU combination and reducing the energy footprint. During practical use, most of the regular Windows programs can be used without any concerns. Only in the case of demanding 3D applications do considerable restrictions apply.
When it comes to the typical tablet benchmarks such as Geekbench or Sunspider, the Microsoft Surface Pro is in a league of its own as it is able to outperform all its rivals by a considerable margin.
PC马克7，微软Surface Pro的戴尔XPS13和宏碁Aspire S7-191与4813点实现相同的结果。的很大一部分可以归结为双声道模式的RAM模块和超高速固态硬盘。唯一的改进是可以做的。将升级到一个更好的CPU-GPU组合，降低了能源消耗。在实际使用过程中，最经常的Windows程序，可以使用没有任何问题。只有在要求苛刻的3D应用程序的情况下相当大的限制。
当它涉及到典型的片剂等基准测试软件Geekbench的Sunspider，微软Surface Pro是在它自己的联赛，因为它是能够超越所有它的竞争对手幅度相当。

Storage Device
Micron's Real SSD C400 is the storage device of choice and is connected to s SATA III port. The SSD can take full advantage of the bandwidth that is available. Sequential reads top out at about 500 MB/s while sequential writes are measured at about 87 MB/s. This is a limitation of the SSD firmware and the type of flash chip arrangement that has been used. The 128GB version of the Crucial SSD which is probably the same as the one adopted for the 128GB Surface Pro should be a little faster in this respect. Normal workloads don’t include much writing to the drive and there is also an issue of much of the storage space being occupied by the operating system. Following harsh criticism from users and the media, there is at least a note of caution on Microsoft's product website that warns of the fact that the system software takes up a sizable part of the storage space. Here is the math: Of the 64 GB in total, the user has about 26 GB available for programs and data. Expanding the storage capacity is possible with an SDXC memory card or via the USB 3.0 port with an external drive.
Graphics Card
Intel's HD Graphics 4000 has a clock speed of up to 1050 MHz in the Microsoft Surface Pro and is not subject to any throttling. During 3D Mark 11, a score of 626 points is achieved while 3D Mark Vantage produces a score of 2935 points. The performance during OpenGL Shading is about 5537 points in Cinebench R10, and 15.78 fps in Cinebench R11.5. These scores are average for a device of this class running Intel HD Graphics 4000. More results can be found in our comprehensive GPU benchmark list.
While running on the battery, the GPU runs at a frequency of only 350 MHz, which leads to a considerably lower result in Cinebench R11.5 of 6.67 fps. With the power connected we weren't able to detect any throttling on maximum utilization.

Gaming Performance
The gaming performance is sufficient to play leisurely PC games smoothly at low resolutions and reduced quality. This is only possible with the power adapter connected. During battery powered use, the reduced clock speed of the GPU takes its toll leading to a reduction of the frame rate anywhere between 30 to 50 percent depending on the game. Games specially developed for tablets such as Angry Birds Space or Galaxy on Fire 2 HD are always a viable option due to their minimal processing demands, and shouldn't pose a problem when running on the battery.

Emissions
System Noise
The cooling fan is operational at all times though the noise is only audible from being very close to the device with a low processing load - we measured about 29.5 dB (A). This is the scenario that is common when the tablet is running normal workloads that include basic productivity, Internet browsing and media consumption. While running several different tasks in parallel, the system noise increased to 32.6 dB (A), and increasing furthermore to 38.2 dB (A) with a medium processing load, finally exceeding 40 dB (A) when the processor and the graphics unit are both loaded. Particularly with medium and high utilization, such high noise levels have to be endured due to the type of hardware in use. ARM and Intel Atom processors are able to run at much lower TDPs that allow them to forgo cooling units, unlike the Core i5 processor in the Surface Pro, which keep noise levels down improving the user experience. But these processing units aren’t able to match the performance levels of the i5 processor. At least these noise levels in the Surface Pro are only noticeable when a substantial processing power is actually required.

Temperature
The Microsoft Surface Pro always feels warm. Regardless of whether it is subjected to a low processing load or fully utilized, the difference only amounts to a few degrees Celsius. With a minimum of approximately 30 °C and a maximum of just over 40 °C, the surface temperatures never become unpleasant. The cooling system is conceived for working as silently as possible with a low processing load, while not allowing the internal components to get too hot with a high processing load resulting in relatively constant case temperatures.
(±) The maximum temperature on the upper side is 40.3 °C / 105 F, compared to the average of 35.4 °C / 96 F, ranging from 19.6 to 60 °C for the class Convertible.
(±) The bottom heats up to a maximum of 40.6 °C / 105 F, compared to the average of 36.8 °C / 98 F
(±) In idle usage, the average temperature for the upper side is 33.2 °C / 92 F, compared to the device average of 30.3 °C / 87 F.
(±) The palmrests and touchpad can get very hot to the touch with a maximum of 39.4 °C / 102.9 F.
(-) The average temperature of the palmrest area of similar devices was 28 °C / 82.4 F (-11.4 °C / -20.5 F).
Speakers
The audio reproduction is suitable for basic tasks which is also the case with most other tablets. Concentrated in the high frequency range with little mid-range or bass frequencies, the speakers should suffice for watching short videos online. Substantially better audio quality is achievable with the aid of headphones, which are more or less obligatory in public areas such as trains or waiting rooms in any case. External speakers can also be connected via Bluetooth, USB or the 3.5 mm jack.

Power Consumption
The power consumption (measured from the power supply) is substantially higher than those of other conventional tablet PCs. With a minimum of 8 watts and a maximum of 43.2 watts, the values are familiar to us as they are about the same obtained from the current crop of Ultrabooks such as the 13 inch Asus Zenbook Prime UX31A. In order to achieve half-decent battery runtimes in spite of such high power consumption, Microsoft has included a 42 Wh battery in the Surface Pro. There is no way to add to this capacity at the moment. Any maintenance tasks must be done at an authorized service center.

Battery Runtime
With the Battery Eater Readers Test (maximum possible battery life, minimum display brightness, wireless modules off, power saver mode), the battery falls just short of the 7-hour mark. The Microsoft Surface RT for example, is able to hold out for more than twice this time despite its smaller battery. During the more realistic WLAN test (power saver mode, approx. 150 cd/m² display brightness, wireless modules on), the battery life falls to about 5 hours - which is about 4 hours less than the result achieved by the Surface RT. With the Battery Eater Classic Test (minimum possible battery life, maximum brightness, everything on, high performance profile), which more or less represents continuous conversion of audio or video files, our test device ran out of juice after 1:33 hours.
Verdict
Microsoft's attempt to combine a tablet and an Ultrabook has been a success in almost every respect when it comes to the Surface Pro. The significantly improved processing power which is effectively identical to that of an Ultrabook, comes at the expense of a few significant disadvantages though.
In terms of the mobility, a comparison to the established tablet rivals reveals a considerable amount of compromise, while the battery life is about half as long and the weight is almost double. The actively cooled system is another issue as the Surface Pro is a pretty noisy device compared to the other tablets in its class.
But, users are able to put to use a full-fledged version of Windows 8, which allows you access to the full gamut of applications that are applicable to x86 hardware. Accessories are easy to find and are light on the wallet. The limited number of ports and the low graphics performance are some disadvantages that many might be able to overlook if they are looking for a tablet that is able to offer the same performance as an Ultrabook.
Many buyers would be definitely looking at the 128 GB option of the Surface Pro as a lot would run out of the storage space available on the 64 GB version. There is no way that a user can increase the storage capacity and there is also some performance issues associated with the capacity that needs to be left free on the SSD to enable its maintenance functions.
The display doesn't provide anything out of the ordinary with the exception of the Full-HD resolution. Brightness, contrast and of course, the glossy display surface are standard for this class of device. Along with the obligatory touch surface, there is provision for control with an input pen which is included with the standard delivery (not tested here) and should prove to be better suited to some tasks.
The Touch Cover keyboard which also serves as a protective cover for the display, improves the typing experience considerably when compared to using the on-screen keyboard. On the other hand, the additional weight means that the device is almost as heavy as an Ultrabook and mobility is furthermore hampered by an additional 200 grams.
Altogether, buyers of the Microsoft Surface Pro will received a potent tablet with unique characteristics for an estimated price of at least 800 Euros. Mobility, storage capacity and the system noise are parameters that a user needs to keep in mind when considering that this is a first-generation device.
