总分80%,联想ThinkPad E450的表现十分全面。固态硬盘结合实惠的15瓦处理器保证了长电池续航和安静低功耗的运行。全高清的屏幕提供了充足的显示空间。高质量的输入设备继承自更高端的T系列ThinkPad,提供了出色的反馈,同时OneLink拓展坞接口为学生的书桌带来了专业笔记本体验。

这也是联想为它配备适合游戏的Radeon显卡所指向的用户群体。当然,办公用户可能并不需要它,而更需要固态硬盘,这个愿望也由其中的2.5寸三星硬盘实现了。

不过,摆在我们面前的并不是一款完美的14寸设备。较低的TFT屏幕亮度,特别是在使用电池时给我们带来了不小的困扰。磨砂的屏幕表面有些帮助,不过并不大,如果屏幕太暗的话在阳台使用就成为了不可能的事情。它的可维护性(固定电池,风扇无法清理)也十分有限。加上有问题的维护底盖(卡扣损坏),生产商是否真的用心考虑了这些方面也让人怀疑。如果你可以接受这些,也不需要高速固态硬盘或色彩绚丽的屏幕的话,那么它会是一款十分适合校园生活的高性价比选择。

需要更高质量屏幕的用户可以考虑Acer TravelMate P645-S,不过它的售价更高。这款14寸设备有不同的配置型号可选,售价也不尽相同。如果你不介意ThinkPad L450的更高重量的话,它会带来更好的可维护性。不过,它的全高清屏幕也不尽理想,但IPS技术带来了更宽的可视角度和更好的色彩。戴尔Latitude 3440也是一个可以考虑的选择,不过我们并不推荐,因为它所使用的GeForce GT 740M已经有些过时。另外它的输入设备也不是非常实用。
