The Toshiba Satellite R15-S822 ($1,549 direct) is not your typical tablet PC. Convertible tablets usually have 12-inch screens and small, lightweight frames. Not so with the R15-S822. This convertible has a 14-inch screen and weighs 6.1 pounds. It's meant to be someone's primary notebook first, and a tablet second—and there's nothing wrong with that.

The Satellite R15 looks a lot like the Toshiba Portégé M205-S809 convertible tablet—only bigger. The swivel screen has a 1,024-by-768 resolution and is large enough to handle spreadsheets comfortably. The screen is bright, making for an enjoyable movie-watching experience. The IBM ThinkPad X41 Tablet ($1,899), PC Magazine's Editors' Choice for tablets, is 3.5 pounds and a pleasure to carry. The R15-S822, at 6.1 pounds, is more likely to be on your lap or on your desk than in your arms.

In tablet mode, the writing experience is pretty good, and we appreciated the added screen space when writing longhand. Using OneNote 2003 and surfing the Web with the digitizer pen was also a breeze. Another advantage of having the larger screen and, in turn, a larger frame is better heat distribution. Heat is always a concern with tablets, but we hardly felt any warmth under the base.
