I did this with my ThinkPad...then realized OSX is the worst operating system ever.
I love OS X, but when I put it on a laptop the previously ran XP, I really didn't like it at all, it didn't help that a few of the drivers were missing. I ended up going with Ubuntu.
Liking or not liking the big boys (Win / *nix / Mac) is a matter of understanding them more than anything else. I prefer OS X to Win 7 by a very big amount, but that doesn't mean Win 7 is crap, just means I prefer how OS X works. A mate of mine has a new iMac but runs Win 7 on it, he prefers that.
