Issues I still see, and have reported several betas ago: Unexpected immediate shutdowns/crashes (several times since final released) Beach ball pauses when closing dialogs/screens in Windows "Unable to Allocate Virtual Machine Memory" despite scads of disk and memory. Because so many people seem happy, I have to suspect that most of my problems are localized to the Mac Pro.
