Not like: Mission Control - it does not work for my work habits, as I have 12 Spaces, which are viewed easily in three rows and four columns than 12 tiny pictures on the top of the screen. And MC also ****ed Exposé up.
Like: Applications seem to open faster, but as I have an SSD on my work MBP with 10.6, I don't ****ing care about that.
I am seriously thinking about what to do when getting a new Mac down the road in one or two years, as 10.6 Macs will be harder to get then, and I can't work with Lion. For the home machine it is okay, but still buggy.
Anyway, Apple has set its eyes on the consumer, thus abandoning people with more specialised needs I guess. We'll see. If it weren't for Exposé and Spaces and QuickLook and the nice GUI, I would switch to Windows (Linux is out of the question due the applications I use.
