Sony Tap 20

A small all-in-one desktop or an over-sized tablet? It's really a tossup with the Sony Tap 20, which we awarded 4 stars in our review. The 20-inch, 1600-by-900 touchscreen looks good despite its relatively low resolution for such a large, er, computer. A stand on the back allows it to function as a typical desktop, or it can be laid out on a flat surface to use as a large tablet for interactive applications or board gaming apps. Avoid using it like a typical tablet, though. This thing weighs more than 11 pounds and is over 20-inches wide, making it somewhat of a hassle. It may be a bit underpowered for a desktop, but at $880 it's a fun, and mobile, family PC.
