Pros
Cons
“工作用Chromebook。”这是宏碁对于他们新的Chromebook的看法:一台日常用办公设备。第一眼看上去就只要Chromebook有了很大的进步。它采用高亮钢琴烤漆取代了原本外壳花哨的颜色。糟糕的是它很容易吸附指纹。但对于一台工作用设备来说,更加重要的是输入设备的适应性。键盘能够很好的应对在办公室的长时间工作。但对于一台完整的商务设备来说,它还缺少很多的安全功能。
雾面IPS屏整体上来说还是很好的。色彩及灰阶的表现都不错。但是,这块屏幕的俩都不足。办公室中或户外的阳光直射都会对于操作造成很大的影响甚至是彻底无法操作。
其搭载的硬件引起了我们的注意。但是,它无法发挥其完整的性能,甚至在基准测试中被更弱的酷睿m5处理器超越。不过,系统的运行还是十分流畅的,比其他一些Chromebook运行的都要快。
宏碁 Chromebook 因为其出色的发热控制和9小时的电池续航时间而赢得了不错的评分。
宏碁 Chromebook 14 工作版达成了其既定目标:一台有着出色续航能力的日常工作用笔记本。
想要改用Chromebook作为其主力设备的用户应该考虑惠普Chromebook 13 G1。而联想 ThinkPad 13 Chromebook提供更强的性能。
