I am a Mac user thinking of buying a new iMac with the Intel Core 2 Duo processor so that I can run Trainz 2009. I have scanned the Auran forums and gather that Trainz 2006 runs well on an Intel-based iMac with Boot Camp. However, I would be interested in any experience with Trainz 2009. Does it work better with Windows XP or Vista or is there no difference? Is Parallels (http://www.parallels.com) worth the investment so that one can switch from OS X to Windows without a reboot?
