If you want to start testing and playing with different distributions without breaking the installed OS I recommend virtual box made by sun. It's a free download and allows you to run more or less and OS you can get your hands on in a virtual environment it's great for testing and working out which distro you want to use permanently before doing a dual boot or format of your host OS. I run Centos, Mint and Ubuntu on virtual box on my macbook safe in the knowledge that I can't screw up my OSX installation, it's also good for running the VM turnkey linux appliances for offline development/testing of my wordpress site.
