From CNET's Review:
Unlike one of Lenovo's IdeaPad line of consumer laptops, the X220 is clearly a business system. The look and feel, while periodically tweaked, are classic ThinkPad, with a busy keyboard and dual touch pad-pointing stick controls. Still, if we had to have a strict buttoned-down work-only laptop, the X220's combo of small size and powerful hardware makes it the one we'd probably want to have.
