On Wii, it's real fun to play Gamecube games, the only downside being no rumble support...
What's strange, is that if I bought a Sony console, it would probably be a PS2 rather than a PS3, because I'm told that the PS3 can't play PS2 games properly.
Only the very first PS3s are compatible with PS2 and PS1. The more recent ones only play PS3 games.
I think you are mistaken, because I have played Wind Waker on the wii and there was rumble feature, unless you used the gamecube wireless control, which has no rumble feature.
Well, I think it's important to have compability in a console, but I wouldn't give up buying a console because it has no compability.
I have a PS3 slim, wich has no compability, but I don't care because I have the PS2 slim, which is really small and doesn't occupies much space.
