iPad mini: 7.87 inches
Google Nexus 7: 7 inches
Amazon Kindle Fire HD: 7 inches
Steve Jobs famously said two years ago that Apple would never make a 7-inch tablet because the screen size would be too small to adequately "express" Apple's iOS software. So Apple, seemingly in honor of its late CEO's wishes, equipped the iPad mini with a slightly larger 7.87-inch screen. So, does that extra .87 inches actually make a difference? According to Apple, yes. Apple's senior vice president of worldwide marketing Phil Schiller said during the iPad mini launch event that Apple competitors in the 7-inch tablet space have "failed miserably" in their designs, sacrificing a rich Web browsing experience to achieve these smaller form factors. Schiller said the new iPad mini, thanks to its extra .87 inches, offers nearly 35 percent more screen real estate than competing tablets. In all fairness, though, if users are looking for a genuinely petite-sized tablet, the Google Nexus 7 and Amazon Kindle Fire HD might be the better way to go.
