Banner~! recommends an article in IBTimes on the search for the ideal size for an ultraportable computer. One device mentioned is Paul Allen's FlipStart, discussed here recently. After watching early users fumble and nearly drop an early version of the FlipStart while trying to perform a three-finger salute, designers ended up including a single key labeled "CtrlAltDel" in the version that will be shipping soon. From the article: "Each device maker... has a different sense of how small an ultra-mobile can get before it becomes impossible to use. For instance, Microsoft thinks the tiniest screen possible measures 7 inches diagonally, but FlipStart Labs settled on 5.6 inches."
