Pros
Cons
戴尔的Latitude E5000系列在我们测试的各个方面都表现优秀。这要从机身说起,因为它非常坚固同时不失美观。
它几乎没有任何工艺品质问题,不过我们希望在后续机型中能够增加维护底盖,或者可更换电池的设计。
可能最重要的部分是输入设备。它的键盘给我们带来了舒适的体验,不过键程略显不足。这台测试机唯一的真正问题是TN屏幕和它的有限可视角度范围。它应该至少有一个更明亮的全高清屏幕版本可供用户选择。如果屏幕品质可以更高,它的得分还有提升的空间。这台Latitude的性能十分平衡,在测试中相比前代机型有明显的优势。我们的测试机的噪音控制也很出色。我们很喜欢它的电池续航表现;这台笔记本电脑可以在电池模式下轻松满足于一个工作日的需要。
戴尔的Latitude E5470是一台成功的主流商务笔记本电脑。不过如果你需要一台办公打字设备的话,则需要外接键盘了。
如果你在寻找一台搭配了更高分辨率的屏幕和高速PCIe-3.0固态硬盘的机型的话,可以考虑联想ThinkPad T460s。最新的Skylake版惠普EliteBook 840 G3也值得参考。同时,需要注意的是这台最新的Latitude E5470在售价上相比这两款设备则低出不少。
