I switched to Ubuntu a couple of years ago. I love how my old machine runs infinitely better than it did on Windows. Once I get my system updated, I'm soo looking forward to getting back into open-source gaming!
[It bothers me, too than Netflix - and Steam? - are so biased against Linux than they refuse to run on it.]
Despite using Ubuntu for a while, I'm a perpetual newb when it comes to any problems - so glad for the forum!
