iWalk is so a fake I'll bet both my testicles
First of all, look at the size of it, its way to big. It looks like a shell has been built over another pda, I am not sure which on, but if you look at the turnaraound movie, look at the firewire port, inside it looks like a place for a stylus, not a firewire cable. ALSO, apple would never make a dial like the one on this unit. it looks awful, plus it does nothing. If you notice, the hand turns the dial, then hits the bottom button and then the screen switches orientation. On the back of the unit, the name iWalk and apple logo aren't even centered on the panel. If it is a prototype, no codes would be on it. You are all falling for a big hoax...
