Pros
+ 众多的机型配置选择
+ 坚固，高品质的机身
+ 个人品味：大量纹理图案
+ 双频Wi-Fi ac标准
+ 不错的输入设备
+ 性能无妥协，运行流畅
+ 256 GB固态硬盘
+ 非常安静清凉
+ 待机模式下非常节能
+ 尽管电池容量小，续航时间十分不错
Cons
- 容易沾染指纹...
- ...且不易清理
- DVD光驱呈一定角度
- 不拆机无法更换升级部件
- 所有的接口都在机身前面
- 无背光键盘
- 平庸的TN屏幕
- 不适合游戏
实际上Acer的TravelMate P257-M-56AX只需稍少降低一些售价就会十分值得推荐。我们认为，720欧元（约4940人民币）是个可以接受的价位，它的售价在未来几个月中应该会降低到这个水平。
在测试中，我们看到的是一款中规中矩，坚固耐用但在技术层面并不出彩的办公设备。它唯一的弱点是平庸的屏幕。
除了近乎完美的散热控制，这台测试机拥有大气的外观，坚固的高品质机身，十分优秀的输入设备，安静清凉的运行，充足的电池续航时间以及足够使用的性能。希望玩一些游戏的用户可以选择例如联想Z51-70或售价更高的搭配的GeForce 940MP2机型。
