Reviews for the Lenovo ThinkPad E490-20N90006GB
Lenovo ThinkPad E490 review – rigid business notebook
Source: Laptop Media
EN→zh-CN Archive.org version
Frankly, the ThinkPad E490 is a controversial device. Which is weird, because it is an exact copy of its predecessor, so one would think that the only way is up and ahead. No, our dear readers, that’s absolutely not the case here. As you may know, if you’ve read the review of ThinkPad E480, it had mediocre battery life and budget IPS panel. Well, this year, Lenovo has definitely upped their game with the battery life and now it reaches more than 10 hours of web browsing and around 9 hours of video playback.

大体上，这个屏幕尺寸常见于亚笔记本电脑，超极本和变形本中。对这三类产品来说这个尺寸都较大。亚笔记本中尺寸最大的机型是采用这个屏幕尺寸。
大尺寸可以让屏幕有更高的分辨率。因而例如字体等的细节将会更丰富。不过另一方面，小屏幕的功耗会较低，而设备也会更轻盈小巧，售价更低。
