What's A Good Starter Linux distro?

alen writes "I've been working with NT for a year now, and I'm getting really tired of it. So I finally decided to learn Linux, after a year of putting it off. I've got an old P2 266 that I'm going to use. Now the next question is what distro do I get? What's a good starter version? I'm just looking to get the feel of it and to play around a little. " This question gets asked periodically - it's always good to hear have a lively discussion about it - I love my Debian but have heard that Mandrake is a good starter distro.
