Bottom line so far is that most users are having very good luck running MediaLab and DirectRT on the new Intel Macs. Note though for Windows 7 that you do need DirectRT 2010 (MediaLab v2008 is ok if you have the most recent version). And BootCamp seems to be the way to go although Parallels has had some positive results also. Fwiw, I am currently running all this stuff on a new MacBook Pro with Windows 7 on BootCamp.
