One more thing. You can install Linux onto a pen drive, which you'll pretty much need to do in order to install it, and just run it from the pen drive for a while and see how you like it. Don't like it, don't install it to your hard drive, just overwrite it with a different distro. Do that till you find the one you like. You can just start with the first one on the list at that website, then go to number 2, then 3, etc. Once you find one you like, install it to the hard drive. And again, if you decide a month after that, that you don't like it, overwrite it with a different distro.
