I love Lion! When they announced it I was so disappointed - Launchpad just looked like a fancy applications stack, I never used Spaces so was not excited about Mission Control, I didn't believe MultiTouch would feel as smooth as it does, and, based on NEVER using the full-screen option on iLife, thought I would never use full screen on anything. However - they all work and look differently to how I imagined, it all seems to make sense, flicking through full screen apps, controlling everything at once, and bringing up launchpad from wherever you are. I like the new UI as well - people are moaning, but trust me there would be a lot more people moaning if Apple went for something radical and it failed. Sort the fans out in 10.7.1 (ie. Why do they run when I'm not even doing anything) and it will be great.
