Cool i didn't realise this before. It does look as if this could maybe be a sign of portability. That would be good :).

I haven't actually played on it on the ds wifi so this is just what I have heard from other people.

I think the wifi connection on the ds and stuff is alright but they should make it so each console has one and you don't have to change it with each game. That would make sense. But judging by what everyone else has said I think nintendo are really just trying to make it more secure and stuff.
