The controller is the most important thing for me - I can play NES half the devices in my home, but can only use the controller in a limited few of them.

Emulation's biggest curse is the what I call MP3 syndrome - so many games, so little effort, and no desire to stick to one title. "Aw dammit died again." = Savestate, toggle game, come back to it later (maybe)

I just can't stick with games that way. Which is why I hit next on my ipod way too much.
