Long time ago my dad bought a few netbooks and they came with Xandros pre-installed. It wasn't much of a choice to be honest (all my friends, school, every other PC was running Windows). And I never give it a chance because there was a desktop with Windows so I used that instead.
Times goes buy and the Xandros version was not going to keep up with my needs and I've switched to Ubuntu Remix (very cool at the time) and then I've got to experience Ubuntu 09.10 with Gnome. And that was a game changer for me (I learned a lot on how Linux works under the.hood) but I kept Windows machine just for gaming (until last year).
