The business-oriented Lenovo ThinkPad X1 has a few quirks, but is otherwise a very impressive business-oriented ultrabook with strong crossover potential.
The Lenovo ThinkPad T420 is as straight-up and unassuming as a business laptop can be on the surface, souped up with faster performance, long battery life, and a flexible selection of ports under the hood.
The pixel-dense Dell XPS One 2710 is one of the best Windows-based all-in-ones available and, barring a new iMac, an easy high-end recommendation.
The Lenovo ThinkPad X220 packs in a new Intel Core i5 CPU and can run all day (depending on how you use it). With a 12.5-inch display, it's just a bit smaller than a 13-inch laptop, and it feels like an excellent compromise for frequent travelers.
