Hey, let's not forget that the DS has a homebrew scene as well. While I doubt there's potential for Playstation emulation, I've heard the SNES isn't out of the question (alas, I can't prove it since I haven't tried). Also, there's some untapped potential beyond classic games!
Also, DS owners should look into the Phoenix Wright/Ace Attorney games if you haven't already. You'll never question your purchase again.
