The fact that you need to ask is a bad sign.
I work in technology. I have stopped purchasing consoles and "Exclusive" bits of hardware where ever possible. Console needs to die, not because I am a PC gamer, which I am, but because people should not be asked to shell out $$$ just to play on an exclusive platform. The different in cost and performance are less of the issue compared to vendor lock in with game titles.
Regarding the Retro community. There are many fans like http://byuu.org/ that focus on 100% accuracy with emulation. Compound that with available Up-scaling technology and you can make an older titles visually look better without altering the original code or game-play. I cannot tell you how terrible many game ports have been and show a clear trend that game companies do not respect their IP and would rather damage it in the pursuit of money than to do right by it or the gamer community.
Do we really need to get into Nintendo's terrible history against gamers to add more fuel to this?
