It's not too far fetched pipking, the only restraint is the screen size and battery life. Remember, the GC's processor is smaller than the average fingernail, so I'm sure it's possible. Just not likely to happen yet though.

As for the control stick, I have a great idea. How about a slightly smaller version of the C-stick on the GC? It would be the right size, yet would also be easy enough to manage. Sound good?
