I own one. I do most of my mundane stuff on it. Office, web, etc. But I have a PC also, so I don't run games on it, except for the simpler ones. WingNuts, Pocket Tanks, popcap stuff.
Mac OS X has some OS-hosting subsystems built right in, which is why it can share the desktop with OS 9. I have heard that VirtualPC isn't too bad. It contains a PC-on-a-card. With it, you can run Windows XP in a window on your OS X desktop. I looked at it a while back. It'll set you back almost 200 to get the card with the bundled XP. It ought to be able to run SFC2/OP. If you research it and find out for sure, I'd like to know.
