I have a quite new 120GB Zune but the hold switch broke and they aren't sold (or repaired) in Europe.
It's still ok because the touch thing doesn't really work just through a jeans pocket, you have to actually tough with you finger.
Still you have to delete music and re add it if you add album art after you synced it which is shit and it's a bit slow and skippy being a HD player.
I'm tempted to get a smaller flash one as well. I had a HD and a flash one before. The only thing is when the one song you want to listen is on the larger one which is miles away or whatever, flat etc.
