1. A Large DisplayTablets aren't all that useful when they feature small displays. The Dell Streak, for example, came with just a 5-inch display. The iPad, on the other hand, offers a 9.7-inch screen. Some upcoming tablets, like the Motorola Xoom, will offer 10.1-inch displays. The iPad's screen is the right size for most customers, and moving up to a 10.1-inch display would be just as nice. But going under 7 inches would be a mistake.
