I remember the days when there was a clear distinction between Mac gams and PCs. Most PC games weren't available on the Mac, and the mac only games, as much as I enjoyed them, weren't on the same par as most PC games (generally speaking of course).
\These days, however, apple has gone out of it's way to make sure they can load as many types of software as they can, and most mainstream games for the PC are also on the mac. Of course, SFC games aren't among those on the mac, but from what I hear this is because Taldren chose formats that won't port easily to the mac interface. Too bad, really, but great games none the less.
So far my iBook has exceeded all my expectations, I'm very glad I made this choice. The best part was loading everything from my iMac to it: simply plugged the two together, made an extremely painless connection (few numbers and a click) to the iMac and downloaded everything I wanted off of it. Sweet sweet sweet.
