Next, to all those Mac zealots who are calling Intel a copycat for making a small prototype PC, shut up already. Your beloved Mac Mini that Intel is shamelessly knocking off is itself a shameless knockoff of the Cuppucino PC's which have been around for years. The biggest functional difference is that they're cheaper and are available with a DVD burner, and the biggest stylistic difference between 'em is the pattern of vents on the top of the case.
So just quit it. Tiny PC's have been around since the freakin' Timex/Sinclair. Furthermore, the original Mac interface was borrowed from Xerox. Steve Jobs' NeXT cube design was lifted from Pixar.

And the ZX80 was even smaller, if I recall correctly.
