Howdy - I used Apple's Boot Camp app (the 'beta version' jarvis24 refers to above) to partition the hard drive on a relatively new MacBook (1.83 GHz Intel Core Duo and 1.25 GB SDRAM) and installed XP Pro. At start-up, you just hold the 'option' key down and you are presented with the choice to boot to OSX or XP. Very simple. I've not used DirectRT, but Medialab has run flawlessly on the Windows partition. I concur completely with the comment by jarvis24 above that it's a great way to use the product if you are an Apple person.
