I'm not evaluating it from the release notes--I was rereading them to make sure I wasn't just missing some major improvements I just hadn't noticed while using it. I don't think it's well designed at all, and it's certainly not polished at all, which is an important part of good design.

I suspect that most of the major changes have been on the back end, and that it is a substantially better platform to develop on. Unfortunately, that doesn't affect me at all as a user. I want to be able to run terminals and a web browser and not much else (and I don't think I'm alone in that), and so making Gnome a better environment to develop against is unlikely to make my life any better in the foreseeable future.
