Lenovo ThinkPad T450. Test model courtesy of campuspoint.de

它物有所值——需要承认的是，这么说有些敷衍，T450也完全称不上“便宜”。不过，现实终不够理想：联想为这款售价超过1000欧元（约6570人民币）的笔记本电脑采用低质量屏幕的决定让人很难理解，这可能只是为了凸显T450s更高价位的价值。

在T450整体优秀表现的衬托之下，这款TN屏幕显得让人更加失望。它的机身、连接性和输入设备，与更贵的同门师兄几乎毫无差别。另外，它的噪音和发热量也相对很低。除此之外，我们的测试机的Core i5处理器与8GB内存加上固态硬盘的配置非常均衡，完美地平衡了性能与成本。它的电池续航还可以更好，不过这个问题可以通过售价不高的更大容量电池得到解决。

简而言之，ThinkPad T450可能会对需要在家工作且常使用外接显示器的用户十分有吸引力。

我们十分建议对此机型有兴趣的用户考虑接受T450s较高的售价，或考虑竞争对手惠普或戴尔的产品。它们都提供了（至少可选）更加明亮，高对比度且可视角度更稳定的IPS屏幕，以及完全可以和ThinkPad一较高下的质量。
