Let's hope you make good experiences with FOSS (Free and Open Source Software), but if you don't please don't give up =D
It's called "Ubuntu
" by the way, and it's a good starting point for beginners and average users. I, for my part, use Debian
because I'm experienced and trying different things (right now, I have a "stable" system plus backports
plus a few "testing" packages - maybe I'll stay with that).
