It seems that the main reason for upgrading to 2.0 is to use the Web Browser built into it.. But with Web Browsers being available as homebrew (OK they need some work) I'd not be too worried about this...
The real trigger to upgrade will be when a game you REALLY want comes out that requires you to have 2.0... (assuming that the game won't be "crackable" to run from an iso image...)
