Initial Thoughts on iTunes 11 and Remote 3.0
As I feared, No voting feature remains (as from iTunes DJ).
Up Next is the alternative approach now, but you need to pair your Remote (2.x or 3.0) to iTunes 11 (via Home Sharing or PIN) and therefore EVERYONE doing this would have full control to edit whats in the queue, delete tracks, re-order stuff.
Not like the fairer and fun iTunes DJ.
Up Next for regular family use is better than more niche iTunes DJ I agree. So I can see why it changed. But then I don't see why the 2 systems can't co-exist.. Apple would just need to add back a special playlist, that unpaired remotes can manipulate via voting, without giving them full control. Job done.
Regarding other stuff. Playlist folders is useful addition. I have loads of library maintenance type playlist and I can now group up and hide away. You can also nest folders in folders.
General browsing in Album view in nice as is searching in compact view. I agree with earlier poster that having album artwork as a choice for the columns in list view will be missed.
I've had spinning beachballs quite a bit during Match, Store and Sync operations. Hope it's only just early initialisation issues.
Remote 3.0 is better overall. It seems quicker than earlier releases with a more logical layout. It still works with iTunes 10 for iTunes DJ.
