Pros
Cons
连接上时尚而不失坚固的键盘,Spectre x2可以有效的用作桌面笔记本电脑。USB C型接口被用作充电接口,它可以通过附带的转接埠连接现有的A型接口外置设备。平板背面的主相机可以拍摄非常不错的照片和视频。我们很久没有在Windows平板中感受到这一点了。另外,RealSense相机支持3D扫描——至少以后会。它可以用于测量结构深度,例如脸型。
Spectre x2也有一些还算可以接受的缺点。一些用户可能会怀念标准SD卡的读卡器。如果倾斜一点平板它的支架会错位。它的电池续航还不错,不过考虑到售价和酷睿M处理器,它应该实现7到8小时的上网时间而不只是测试结果的6小时。
仅仅达到Surface Pro Core M3水平的运算性能让我们十分失望。潜在用户应该考虑它的m3-6Y30版本(2x 900 MHz),它应该在普通用途下提供更好的节能。它们的售价相同,不过较“弱”的机型搭配了LTE模组。如果需要性能的话,则需要考虑微软的Surface Pro 4酷睿i5/i7版本,它们也搭配了更快的NVMe固态硬盘。
实际上尺寸稍大的惠普 Spectre x360 13变形本搭配i5-6200U,性能更高,在我们的测试中得到了84%的分数。微软的Surface Book,Acer的Aspire R7-371T-52EL,联想的ThinkPad Yoga 12一级微软Surface Pro (i5/i7)都提供了相同水平的处理器性能。尽管需要高性能的用户可能需要考虑这些设备,不过也不一定就一定排除Spectre x2。它作为二合一设备十分实用。它的M7处理器的应用程序性能还有一定的竞争力。
