The last few months have seen a deluge of ultrabooks, with companies tripping over one another to offer sleek profiles with tapered teardrop designs and roughly the same specifications. And now there’s Lenovo, breaking the mold by sticking to what it knows best: black boxes built for work. The ThinkPad X230 is one of the latest ultraportables to join the Lenovo fold, sporting Intel’s recently announced dual-core Ivy Bridge processor, and (arguably more importantly) Lenovo’s new Precision keyboard — the same comfortable yet controversial set of chiclet keys the company’s added to all its new models. The 12.5-inch ThinkPad X230 I reviewed is equipped with a 2.6GHz Core i5-3320M processor, 4GB of RAM, a 320GB 5400 RPM hard drive, and Intel integrated graphics — it falls close to the middle of the X230 lineup, and is priced at $1,249 (as configured). With the exception of the revamped keyboard, Lenovo has largely decided to stay its laptop course. Is it a winning strategy? I’ll get to that and more, so read on.
