Pros
Cons
Yoga Book在我们心中占据了一个十分独特的位置，它运行安卓的型号也表现十分不错。实际上，在一些方面甚至超过了Windows机型。这台设备的设计十分特别，看到“表带”式屏幕转轴也让我们十分兴奋。背光的Halo键盘看上去十分美观，同时也很适合实际日常使用，不过我们不建议在日光下使用，可能在强光下还是传统机械键盘比较适合。
Yoga Book在电子笔记方面非常出色。它对于需要在移动中记录很多笔记或同时需要触控屏幕和绘图板的用户十分适合。iPad Pro 9.7无法满足这些需要。但是偶尔这台设备也需要一些时间识别输入内容或执行任务。感兴趣的专业用户应该在购买前花一些时间试用（特别是绘图板的实际使用感受）。
它的性能和屏幕表现都十分不错，但不算出色。它们可以满足日常使用的需要。它的屏幕在色彩准确度上表现不足，可能无法达到专业用户的标准。另一方面，让人欣慰的是它在运行中几乎不会变热，可以保持最高性能运转。而优秀的扬声器、坚固的机身和非常灵活的输入方式都让联想 Yoga Book Android可以满足各种不同情况的需要。
兼具实用性、功能性和灵活性，同时没有缺陷：Yoga Book Android无疑是一台特别的设备，但它可以为工作带来很多乐趣。
如果你不需要Windows 10的话，那么我们建议参考一下这个安卓机型，它在一些方面胜过了Windows机型：电池续航和屏幕表现。
整体上，联想的这台独特工具十分适合需要便携绘图板的平面设计师。Yoga Book在设计和外观上也十分引人注目，特别是雅致的机身和独特的屏幕转轴。这台设备提供了众多功能而没有明显弱点。我们十分建议对这类设备感兴趣的用户考虑一下这台Yoga Book Android。
