I reckon about as impossible as with the new one 😉 I don't see any new buttons on it.
Stuff the games, I'm more worried about not having the playlist-to-go feature, which IMHO should have been in the iPod software from day one. I guess the reason some people are annoyed is that it doesn't seem to be a hardware limitation - more a conscious decision to exclude owners of the older machines, when it isn't even performanced-based - ie: it's not worth running the lists, or the playlist-to-go on the old ipods.
