I've been mainly on Linux for 20 years now (damn already?), what started as a cheap computer with second-hand parts with a more powerful windows machine mostly for games is now a powerful machine in its own rights with an outdated windows one gathering dust right beside it... It's not perfect, but I don't have to spend half an hour removing everything useless I can. (Or have Microsoft assume I have nothing better to do than watch a full presentation on how edgy their new browser is. I'm not going to forgive that one.)
