it's being done all the time with desktops, but laptops are still a bit more finicky, due to all the integrated hardware they have. I'd be interested to know as I plan on putting OS X on my DS3R when it's built to get some Mac experience (they're getting more and more popular. if I have any hopes of supporting Mac in the future, I need to know how to use it!) and thought if it's possible, maybe pop it on my laptop as well.
