To be honest, it's difficult to care too much if you're not prepared to give it a go and see what you think of it. Do you need people to do all your thinking for you? Not meaning to be rude, but you're the best person to decide what a particular piece of software means to you.
I'd never talk anyone out of trying it... after all, you can't beat the price. The only caveat is if you're a computer novice, Linux can be a difficult OS to use... depending on what you want to do. Setting it up for internet and email is very easy... setting it up to play Windows games is a bit harder. Ubuntu is definately the easiest distro to start learning Linux with... and if you want to learn it, I would highly suggest you try it.
