As far as a handheld development machine, the Pandora comes to mind: http://en.wikipedia.org/wiki/Pandora_(console) http://en.wikipedia.org/wiki/Pandora_(console) Looks pretty powerful, roughly the size of a Nintendo DS. Of course, it won't replace a laptop... the keyboard size alone. But if I could sync code between the Pandora and my laptop and compile stuff on-the-go. The Pandora could function like notepad for writers... but for programmers. Its usefulness in developing for windows applications would be very limited, however.
