Buyout Xbox live.
On a more serious note, a better way of adding people. Friend codes, I understand, but perhaps something more like an approve friend thing, kind of like what Myspace is going with (Know its a bad comparison, but unlike on Myspace, parents have at least a little control over the Wii).
The big killer of the online system for the Wii is the lack of games that utilize it. I can't name 5 games off the top of my head that I know for sure are online and are already out. Nintendo needs to start including it in more games (IMO, Metroid could have sold hundreds of thousands more with an online multiplayer.)
Another big problem is communication. Mics for Mario Kart por favor? ;D
