A recent survey found that 62 percent of all tablets never leave the home. So why try and make them as big as possible? The Toshiba Excite 13 is targeted at that stay-at-home segment. This mammoth 13-inch tablet, which starts at $649 for the 32GB version, boasts a 1600 x 900-pixel display with support for up to 10 fingers, a quad-core Nvidia Tegra 3 processor, and Android Ice Cream Sandwich. But when you can buy a full-fledged laptop for less, the Excite 13 has a pretty steep uphill climb to win shoppers over. Does it succeed?
