I have!

I actually updgraded the day it came out. Haha!

I've had it a few days. So far so good. At least Plurk and SL work.

I had graphics issues, which apparently was specific to my brand of Lenovo laptop. Insta-crash on bootup. Had like 15 seconds to end AMD processes before the laptop rebooted itself.

really a matter of disabling the graphics card and waiting for an updated driver to come out, which was like... half a day.
