Toshiba grew its Excite tablet line in both directions on Tuesday with three new models to cover every possible category. The Excite 7.7 (which we've tried), Excite 10, and Excite 13 (AT770) all carry a quad-core Tegra 3 chip along with a completely stock version of Android 4.0 bundled with apps like Netflix and Zinio's reader. They keep the slimmer builds of past Excite models but with a more rounded, polished design.
