ThinkPad T440s在我们的商务产品排行榜中占据首位已达一年之久——现在新的T450s非常可能会取代它的位置。这款商务经典再一次凭借全面的表现让人信服,从出色的机身做工到可作为行业标准的键盘质量再到低噪音低发热量的控制设计。整体上,这台ThinkPad几乎没有什么缺点。当然,我们会希望它能再多一个数字视频输出接口和一个内存槽,和容量更大的第二块电池。不过这些并不是严重的问题,特别是当联想解决了前作中的一大问题——不便于使用的点击触控板——之后。因此我们十分好奇戴尔 Latitude E7450和惠普 EliteBook 840 G1(接下来还有840 G2的评测)是否可以与这台设备抗衡。我们一如既往的全面评测将会在不久后发布。
