My wife's MB Pro faced an upcoming support reckoning with Apple, and I just tossed Linux on it. Problem solved ;) I've also used FreeBSD on (non-Apple) laptops in the past. It actually worked ok, I even had wireless working (this is very hardware dependent though, and things may have gotten worse over the years for all I know). Based on the rest of your profile I think you might enjoy switching that workstation away from OS X to FreeBSD. Of course, it means some tinkering and looking for new tools to replace the ones you use now, but the tinkering is half the fun... :)
