Yep, that's true. There will definitely be teething problems, and it's often best to let others go through all that crap, and then just step in once it's all settled and enjoy a smoother ride. I didn't bother with the beta of Windows 7, and am waiting a little while to get it now that it's out. The student offer is valid until January, so I'll grab it late december some time, by which time there should be full working drivers released for everything I need.
Saying that, I think that fact that 7 is so similar to Vista (except it works...) means that there's not a lot to iron out which the manufacturer's don't already know about. Take a look at this from the Cakewalk (Sonar) site:
