Watching users fumble and nearly drop an early version of the FlipStart compact PC practically gave Robin Budd a heart attack. The culprit was the three-key sequence, Control-Alt-Delete, required to log off or reboot a Windows PC.

“They would be holding the device in one hand, and they would try to get their three fingers on the keys at one time,” said Budd, senior director at FlipStart Labs, a venture backed by Microsoft co-founder Paul Allen. “You can do it if you’re fairly nimble with your fingers, but it’s sort of a tippy, precarious thing.”

When the shrunken-down laptop goes on sale later this month, early adopters might get a kick out of FlipStart’s solution: a dedicated key marked “Ctrl Alt Del.”
