I'm a proud owner of Apple for the last 4 years. I had frozen osx before, probably once a year for some random things. I don't think it's a big deal However, after I use lion it already crash 3 times in Macbook Pro i7 2010 and iMac early 2011. It all started when i'm using xcode, and then it froze. When I force quit it, then BAMB...all the dots in my opened apps are missing. I thought it was just a finder error, but when I use mission control, I see nothing. No apps at all. Keyboard not responding as well. I can't click on anything, not even the apple menu. So I have to hard reset it. can't wait for 10.7.1. Hopefully it fix it.
