All those reasons point only to one thing: A bloated, form over function slug that is asking to freeze. I was a beta tester for OSX a few years back, and I have used every release since. However, when I really want to get work done I always end up on my Linux box using WindowMaker. It's small, fast, and it has NEVER locked up. Apple has spent too much time making OSX pretty and not enough time making it work.
