By the way, the issues I've had throughout the preview program with the various releases have been numerous and very frustrating (I keep muttering "I signed up for this, I signed up for this..."), and I've posted about 50 feedback items to the program. Sonar, however, has worked pretty flawlessly throughout the experience on even the crankiest of builds, and while my mail or my browser may have crashed uncontrollably, Sonar kept pumping right along, and my creaky old MOTU firewire interface has worked great even with the in-the-box firewire drivers (no legacy driver installs.) For DAW's this OS is looking pretty promising. I'm looking forward to seeing some DAW benchmark numbers.
