Pros
Cons
东芝的这台设备在很多方面都设计的十分优秀：较低的重量带来了出色的便携性，防反光屏幕也具备很高的亮度，电池续航则可以达到12到16小时。它的散热系统也毫无瑕疵：小巧的风扇几乎不会发出任何声音。完整的笔记本电脑性能和优秀的Turbo加速利用率与变形本尺寸形成了完美的结合。
它的镁合金机身仅重1.024千克，甚至低于生产商宣传的1.1千克。因此，Portégé X20w相比其他与Surface Pro 4设计相似（搭配键盘底座）的设备中最轻的。
在和其他360度旋转设备相比它也无可匹敌。12.5寸的ThinkPad Yoga 260重量为1.3千克。
企业用户也可能对X20w十分感兴趣，因为它几乎搭配了所有市场上常见的安全功能——除了智能卡。TPM，指纹感应器，支持Windows Hello的IR摄像机，东芝的BIOS系统，英特尔的Active Management技术等等它都提供了支持。除此之外它还支持AES手写笔，这项功能也与它较高的价位相符。
对它得分有负面影响的是一些小细节：我们感觉它的键盘反馈相对较弱。Miix 720在这方面表现更好。较差的摄像头则拉了一流的麦克风的后腿。尽管它的Thunderbolt 3拓展坞提供了各种接口，但出门在外它还是需要转接器才可以连接HDMI或DisplayPort显示器。在这些情况下，这台设备将无法在使用外接显示器的同时通过USB-C充电。
我们可以十分满意地推荐东芝的Portégé X20w-D-10R。它较高的价位可能无法适合所有用户的预算，特别是个人用户或者小企业。
需要一台无降频现象且安静的设备的用户可以考虑采用无风扇散热设计的Aspire Switch Alpha 12。不过，这台设备的电池续航相对有限。相比之下，搭配散热风扇的微软 Surface Pro 4可能更加全面。华硕 Transformer 3 Pro T303UA由于较短的续航可能无法与其他设备竞争。我们正在测试的IdeaPad Miix 720-12IKB则降频问题较为严重，同时噪音过大。
