Well, rockbox is pretty awesome, but I really only like it for the plugins-- the games, doom, rockboy, and other plugins, video player, demos, calculator, etc.
As far as the actual UI goes, I much prefer the simplistic apple firmware UI. I have seen some ipod clone themes, but it's not the same. I was wondering if there is a way to dual boot the apple firmware and a minimalistic version of rockbox (ie. just the plugins) so that in the main menu of apple's UI you have a rockbox option where you can access all the games, etc, while still listening to your music. (and hopefully not draining too much battery life).
is this possible? if not, would it be too hard to do?
