Sony Tap 20
A small all-in-one desktop or an oversized 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 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. Avoid using it like a typical tablet, though. This thing weighs more than 11 pounds and is more than 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.
