I'm new to hubski so I thought I would try to add something useful to the community, not another Apple circle jerk. I really like the new set up. It's extremely quickly, solid, and has an easy layout. I have been using it for a few hours and while it does seem that streaming songs from the cloud is a little slow right now, I can't find a negative thing to say about it as an upgrade. Now if only it streamed music... Check out the article I posted as it does seem to be one of the best I have come across in the 2 hours that iTunes has been out.
I don't see any change that excites me in anyway at all, but it also looks like they didn't do anything that will drive me crazy. Haven't installed it yet, but there are a few things that I hope they have improved that the article didn't mention, maybe they checked one or two off the list.
