Hold on, So its possible to install OSX on my ipod, take it to a computer at school, and boot up my OSX - my computer basically - on the school computer?

I really hope you say this is possible, cos that is so cool.

No, not unless it's an osx image and your school computer is a mac that is compatible with that image, and in that case, it would probably have osx already installed...so then it would be pointless.

The only other way probably wouldn't even be an option for you...
