Good answers, RacerX. And I guess Snood is some sort of game that would run in Classic?
And I just have to repeat one of the basic benefits of using Mac OS X: You can keep your applications open. In OS 9, I always had to _decide_ what to work with. I kept two copies of Photoshop, one using 80 MB of RAM, one using 300 MB of RAM (when I had 512), and I always had to quit the big one as soon as I wanted to use either GoLive, Illustrator or InDesign concurrently. Now in OS X, I just open them all. I'm glad that I can tell Photoshop the percentage of RAM it should use, but somehow I'd rather not, as I fear as long as it's opened, it hogs RAM - even in the background and without images open...
The most important thing, I think, is that you _HAVE_ to try and adapt to the differences Mac OS X has over Mac OS 9 - and you'll not only SEE the advantages, you'll feel them. And use them. And start to miss the days when you thought OS X was a bad idea. :P
