f2titan, don't bother arguing Macs and PCs with Bill. Bill and I have gone over it a few times, and he's not willing to learn. Not having any real Macintosh experience, he has no concept of what he is missing.
Bill, you really should be less selective with your facts.
The only fact that's relevent here is that there are no modern RC sims available for the Mac. That's unfortunate, and there's an untapped market out there. The best solution out there right now is to buy a PC for RC sims and games. I've got a P4 set up with a KVM switch, so it doesn't take up much room on my desk. I do the vast majority of my computing on the Mac, and only switch over to the PC for diversions. With the KVM it only takes a push of the button to flip over.
Running things such as RC sims in emulation is not recommended.
