Slice is bringing the lowly chiclets into a whole another dimension. Depending on which fingers you place on the home buttons, it'll display a rotary wheel of keys that you can reach allowing you to touch-type without peeking.The app, which works on 7-inch or larger tablets, also brings "easy access" to special characters, punctuation and a numeric keypad, along with a version of Space Invaders to practice on, appropriately enough.
