Well, it'll probably be at least a couple of months before I buy it. So there'll be some time for issues to possibly get smoothed out if not completely eliminated, and maybe more proggies to be made Universal. Maybe even a new version of BootCamp.
Arstechnica recently did a pretty thorough article on BootCamp w/XP, and it seemed to go pretty smoothly for them. Of course I know it's not perfect. But from their experience it seems to work pretty well.
Another thing is that I have a lot of time, money, and effort put into getting and learning several key pieces of software in Windows. So I'm not planning on buying much additional Mac software at first with the exception of Office. So I'm going to be kinda easing myself into the whole Mac environment, not jumping in with both feet. That'll both give me time to get accustomed to it and them time to work out issues and release Intel compatible software. Overall, I'm looking forward to it. 
 
Also, it's built on top of FreeBSD (IIRC), and while I'm no Unix expert, I do have a good bit of experience with Li/Unix types of systems. The terminal, at least, should be pretty familiar.
