Hackers get Mac to run Windows

Yeah this is really neat. I know a lot of people who use Macs but still have a Windows machine around to run certain Windows only programs. This will be great for them. I know some other people who wanted an iMac due to space constraints but didn't get one as they needed a Windows machine.
 
Almost time to buy that dual core 15" Macbook Pro. :D Now I wonder how hard it would to dual boot it?
