Don't do it! I made the change as you want to do and after 8 months went back to windows.best thing I ever did was binning the mac. Very restrictive usage, very frustrating to use and above all, software is hard to find. That being said, if you want to use it for business use, music production, the it's fine. For home entertainment, games etc, it's next to useless.
Yes, other will disagree, but this in my opinion from my experience with a mac. If you have used windows for a while and your comfortable with it, a mac will drive you bonkers. Just closing a window is a pain. I hated it with a passion.
My new windows laptop is actually faster on boot up than the mac.
Tread with caution, borrow one if you can to see if you can get on with it.
