Only had a very brief glance at Unity in Ubuntu 12.04 mainly because it doesn't work on my old laptop without some tweaking. Don't really see any advantage in all that eye candy. That wasn't why I migrated to Linux. If I had preferred form over function, then I would have stayed with Windows.
I love the idea of Unity, but I cannot say that I will like it any more than what I have in previous versions. I am hoping there will be some major improvements with this interface or desktop environment as it does have a lot of potential. It has a great look, but I am a firm believer that functionality and usability comes before appearance!
