I've very much enjoyed using RockBox on my Sansa Clip Zip. It's not only made it a useable player, I play the games often. For some reason, playing an almost microscopic solitaire, or sudoku does something satisfying to my brain.
I see that there hasn't been much action in terms of development. My Sansa Clip Zip is starting to get long in the tooth. And I see that the newer Clip Sport has not been ported yet.
Is there still any activity going on in terms of ports? Or is RockBox kind of in coasting mode?
