Depends on what kind of hardware you are starting out with first off. If you have a macbook or powerbook, you can run Mac OS X with no issues. If its a powerbook, you're pretty much stuck there unless you want to try ppc Linux which I've never been fond of. If its a macbook (has an Intel processor) you can put any flavor of windows on it, any Linux, pretty much what ever you feel.
If you are starting out with a PC laptop or desktop, your simplest bet is a flavor of windows. If you have a fairly new computer, hop on Windows 7, its not great but beats the hell out of vista any day. You also have the option of a Linux distribution (ubuntu, suse, kubuntu is the best from my experience). And if you really want to play around, you can even put OS X on your PC but you'll have to Google around for that one, not sure if answers.com would condone talking about that here.

There are lots of types of computers and different software is written for different kinds of computer. If you have software that is not designed to work on your computer and your operating system, it is no use. Applications need an operating system in order to be able to work. If the application is designed to work on one operating system then it cannot work on others. So if you have a PC, buying Mac software for it is no use. If you have a Mac, buying PC software is no good. Different versions of the same software are brought out for different computers, so you need to have the right one for your computer and operating system.
