I decided to hold off on the laptop, but have been working to install Windows on my Mac via Boot Camp today. A much easier process than the one I remember from the olden days (which involved burning an install disc and lots of hoops to jump through.)
Everything seems to be fine, so far. I've set up a Dropbox folder that I can use to share files with my Mac and I think it'll be good for my productivity to have a kind of distraction free workspace when I'm working in A:M.
