1. Size MattersApple has proven that the size of the display is a key contributor to the success or failure of tablets. Devices with small displays, like the Dell Streak or the 7-inch Galaxy Tab haven't performed well at retail. But the iPad and its 9.7-inch screen have. That's because consumers want to enjoy entertainment content and surf the Web on tablets, and the bigger the display, the easier it is to do that. Luckily for HP customers, the TouchPad comes with a 9.7-inch screen.
