In Review: Dell Latitude 12 E7250. Test model courtesy of Dell Germany.

商务本很少让人眼前一亮;它们通常以坚固性和全面的功能见长。戴尔的Latitude E7250给我们带来了书桌上的又一员新兵:它的机身采用了高质量材质如碳纤维和镁铝合金,它的设计十分便于维护。电池的续航时间足以支撑长时间的飞行而不需连接电源。

这些方面又结合了典型的商务功能如丰富的接口,长时间质保和全面的安全功能。它的无线信号接收效果十分优秀,而屏幕的锐利显示效果和准确的色彩也让人满意。拓展坞接口可以说是个标配,它的输入设备也同样出色。

对于它在负载下的温度我们就不太满意了,实际上它的尖锐风扇声也十分吵人。它的镜面触控屏幕功能可以在定制时放弃,这也可帮助降低机身较高的重量。它缺少VGA接口可能对一部分用户来说有些不便,特别是当你忘记带上转接头的时候。

整体上,Latitude E7250并没有什么特别大的问题,不过如果你已经有它的前代产品在办公桌上的话,更新的必要也不大:新的英特尔处理器并没有快很多,在实际使用中很难察觉到区别,而机身内的其他部件也没有什么变化,前代产品已经提供了很全面的安全功能。

不过如果你需要一款有优秀屏幕和出色可维护性的可靠商务便携笔记本的话,你大可不再犹豫了。它的售价相比联想和惠普的同类设备来说十分合理。
