简洁,但并不出色。Acer TravelMate P246-M达到了消费级产品的标准水平,而更增添了一些商务产品的质感。不过后者通常拥有的一流输入设备、不错的磨砂屏幕、方便的维护升级、低发热量等特点在这款笔记本中仅在一定程度上得到了体现。它的机身质量仅属于可以接受的水平,而在我们看来较生硬、反馈较弱的输入设备是它最大的问题之一。另外它的接口配备和维护空间也十分有限。
Acer TravelMate P246-M在低发热量、不错的性能、长达8小时的电池续航(无线上网测试)这些方面的出色表现都是它的优势。不过它也仅仅如此了,我们很难找到购买这款机型的有力理由。它的售价也没什么吸引力:我们的TravelMate测试机型售价高达620欧元(约4427人民币),在这个价位有很多整体水平更高的产品。
值得一提的有来自戴尔的Latitude 3440,来自富士通的LifeBook E544,联想的ThinkPad L440,和惠普的ProBook 645。Latitude 14 3440搭配Core i5处理器的机型售价不足600欧元(约4287人民币),不过它的键盘质量也不是很高。在这个价位更有竞争力的对手是LifeBook E544,它售价645欧元(约4606人民币)。实用的输入设备,低发热量和强大的连接性为它带来了80%的总分。ThinkPad L440起售价为660欧元(约4713人民币),搭配了HD+分辨率屏幕和顶级输入设备。不过它的机身相对较厚。ProBook 645 G1得到了更优秀的总分,不过配备了相对较弱的AMD A6-5350M处理器,售价也较高。
