Pros
Cons
宏碁TravelMate P449是“无所不能，便一无所精”的。它是一个全面的设备，涉猎甚广。它大小适合，机身体积小，重量轻，便于携带，但是屏幕仍然足够大，可用于多任务办公。机身看起来有专业而有吸引力。键盘看起来很不错，和性能足够用。显示屏提供高对比度和艳丽色彩。风扇仅在极端负载下才会发出噪声。温度管理良好，即使在满负荷条件下，设备仍保持低温。端口众多，有5个USB端口，2个显示器选项端口和一个以太网端口，电池足以支撑一整天的工作。
对于那些需要便携且续航持久的机器的用户来说，宏碁TravelMate P449是一个很好的选择。尽管它有一些缺点，如果预算有限，这将是一个不错的选择。
TravelMate做出了一些牺牲，以获得有竞争力的价格点。俊朗的外壳很薄，感觉很廉价，因此长期耐用性将是一个问题。触摸板不同步，而指纹读取器几乎没有用。屏幕昏暗，几乎不能在明亮的光线下使用。大多数连接端口都很慢或已经过时，而Skylake 处理器已过时，并且严重节流。
即便如此，宏碁TravelMate P449-M-7407仍然是1000美元以下商务本市场上的一个引人注目的选择。然而，联想 ThinkPad E470 的价格难以忽视。约720美元，E470提供更好的性能和质量，类似的续航时间，一个良好的IPS屏幕和一个独立显卡。对于130美元以上的价位，ThinkPad可以配备Kaby Lake 酷睿i7-7500U的处理器和16 GB的内存。请记住，这些机型不附带操作系统，只能在教育市场上获取。对比TravelMate，ThinkPad E470更值得推荐。但是，如果E470无法获取，P449是一个不错的备选方案。
