How about handspring?

And BTW, since the word "handspring" is now probably more well known in relation to the Visor (similar to Palm Pilot), let it be known that what a handspring *really* refers to is a gymnastics skill where one starts with both feet together (or one slightly in front of the other if you're on a 4-inch balance beam), bends the knees and lowers the arms, then springs backwards, landing on both hands, then continues over with legs together (or split, if you're on the beam).

How some executives thought this would be a good name for a handheld computer is beyond me.
