I'd stay far away from Vista right now if you're in the pro-audio world. WAY too many incompatibilities to list and it's been driving the end users nuts.
However, at the same time us Mac users got shafted too with the intel processors, so all the software has to be upgraded to universal binary. So in a way, this problem along with the Vista problems are related somewhat, though I find that on the Mac the programs run smoothly from the start and rarely crash anyway. I'm waiting for my Cubase 4 software to arrive - it's killing me that i can't run my old version of SX on my new mac for the time being.
