You people are lucky. We have iMacs at our school. When we had Windows, anything could run on it. They even had me make a typing program. (Didn't work to well. Got it made then we switched to iMacs.)
Well, you have to admit. With everything Mac is making, will Windows still be good? Vista already has flaws. Game Maker on the other hand, I can see it dead. I hate to see that, but I do. If you learned how to make a operating system or even something little, would you use a program that makes things harder.
I hate to say I won't use Game Maker, but I know I'm going to learn c++ sometime.
