Well, I'm glad for you guys, but my experience with 12.10 wasn't that smooth:
And until multi-monitor support gets better, there will be no 12.10 for me...
on the optimus support. . . Nvidia says they're working on it, but I wouldn't hold my breath. It definitley won't be working out of the box on 12.10, but progress is being made.
I am somewhat upset that they are sticking with kernel 3.5, and they had said early in the dev cycle that they would move to 3.6 if it was looking stable enough. Oh well.
