How long before it happens? Current smartphones can't even handle GameBoy Advance, so this thing will need some pretty good internals. Also, it would be nice to see an ecosystem of game developers for the iPhone emerge: innovative apps taking advantage of the iPhone's interface, possibly even free. I can see adventure games and sims like Viva Pinata doing very well on the iPhone. No doubt ScummVM will be iPhone compatible within 24 hours of it's release - which is, unfortunately, not for a horrendously long time.
