联想再一次只在前代产品上做出了很小的改变就实现了一款成功的产品——ThinkPad X250是在发布于2013年底的X240之上的谨慎进化，恰到火候。
当然，这个连续性不一定是个缺点：它坚固的机身，广受好评的ThinkPad键盘和低噪音在之前就已经表现非常优秀，并不需要做出改变。对于十分适合办公使用而值得推荐的全高清屏幕来说也是如此。遗憾的是售价较低的机型经常仅配备了WXGA分辨率的低质量TN面板屏幕。
另外一个优势是来自Broadwell处理器的更高性能，由于生产工艺的改进而不需要更高的功耗。ThinkPad的老用户可能也会为回归了的指点杆独立鼠标键感到高兴——如果联想能够为点击触控板也恢复实体按键就更好了。这成为了竞争对手如惠普和戴尔的一个优势，在它缺少第二个内存插槽和较少的USB接口方面也是如此。
整体上，这台ThinkPad与“出色”的成绩失之交臂，不过它依然可以在亚笔记本分类中夺得首位。学生和教师可以参加联想的教育计划来得到ThinkPad X250的折扣——如果考虑一下它的耐用性的话，它比相似的消费级机型略高的售价也就十分容易接受了。
