更新的硬件，更大的屏幕，更长电池续航——它有什么不值得喜欢的吗？Yoga 3 14相比前代产品Yoga 2 13在不少方面有了改进。尽管它的屏幕尺寸增大到了14寸，而使用了更小的电池，但新机型仍然提供了更好的性能与明显更长的电池续航时间。256GB的三星固态硬盘在开机、关机和启动程序时都速度极快。这款变形本在日常使用中也相当安静，而在高负载下也不会特别吵人。作为消费级产品它的输入设备十分实用，且键盘提供了背光，这是个非常方便的功能。它的各种使用模式都十分实用，尽管我们建议避免站立模式，因为它的键盘没有保护，会与桌面相接触。
遗憾的是新的屏幕并不如前作产品明亮，因此它就更加暗淡了，且只覆盖了sRGB色域一半的色彩。在明亮的户外使用性十分有限，因此喜欢在户外使用电脑的用户可能需要考虑其他产品。一个可能的选择是联想的老款Yoga 2 Pro，它提供了非常明亮的QHD+屏幕（340尼特，3200x1800像素）。在截稿时，它配备i5-4200U，8GB内存，256GB硬盘的机型售价约850美元。华硕Transformer Book Flip也有更加明亮的屏幕，并配备了入门级的独立显卡，因此它的游戏性能略高。Aspire R13 R7也是一个不错但稍逊一筹的选择，生产商官网出售的Haswell架构机型目前起售价900美元。注重性价比的用户可以考虑联想Flex 2 14，尽管仅支持两种使用模式，尽管售价仅530美元，但仍然配备了IPS屏幕。
