Pros
Cons
当去年ThinkPad X280发布时，我们不禁提问这款经典的12.5英寸笔记本是否已经过时。 ThinkPad X390的发布现在回答了这个问题——的确如此，买家现在更喜欢大屏幕。但是对于ThinkPad X390的我们仍有一些疑问。
首先，联想ThinkPad X390有很多优点，这是联想进步的证明。 ThinkPad X390具有坚固，高品质和纤薄的机身，包含出色的输入设备和大量的接口。商务功能和连接性非常丰富，并且具有三年Premier支持的保修也非常良心。 ThinkPad X390使用户可以非常轻松地更换键盘，这与许多其他小型笔记本电脑有所不同。屏幕哑光，明亮，色域很好。这解决了我们对X280的一个重大问题。 CPU性能良好，ThinkPad X390不会变得特别热，而且几乎完全安静。
有了这么多的有点，是否还有任何缺点？并不多，因为联想不会在这款商务笔记本电脑上犯很多错误。一个不太讨人喜欢的细节是只有microSD卡读卡器，这很糟糕。当设备只使用电池运行时，CPU性能有限，而且X390的键盘明显窄于其他ThinkPad。 X390的升级性能并不理想，特别是完全焊丝的RAM—— 我们希望看到至少一个可升级的RAM插槽。屏幕响应时间较短，Thunderbolt端口仅通过两个PCIe通道连接。同样令人遗憾的是联想没有提供高分辨率的屏幕。
一台完成度极高的机器：联想用X390证明了自己能做对很多事情——但联想内部却有强大的竞争对手。
所有这些都是实实在在的抱怨，但它们有点太挑剔——这款ThinkPad没有大问题。这就是为什么它当然得到我们的推荐。尽管有这个积极的判断，但我们不得不问问ThinkPad T490s是不是更好的选择？后略大，价格更昂贵，没有易于拆卸的键盘，但它有更大的电池，更大的屏幕，可选择更高的分辨率和更宽的键盘。除了那些东西，两个ThinkPad几乎完全相同。最后，如果选择更大或更小的ThinkPad只是一个个人选择问题。也许，联想应该考虑合并这两个产品，因为T490和X390在很多方面都太相似了。
