I've been a Microsoft user since my first computer. I know its not popular but my favorite windows was Me. I didnt have all the problems that nearly everyone else did in the whole world with it
but it was a pre-release edition not sure if it differed any from the final product. Anyhow I had that thing tweaked and hacked perfectly. Also liked 2000, but nothing really after that.
I messed with linux a bit here and there, setup a webserver for several years running CentOS. Never was very proficient with linux though and kind of forgot about it. Well when my last windows laptop died and I decided to build a new desktop I went back to linux... running Ubuntu 12.04 currently. Still learning things, but surprised just what I've been able to do all legitimately free.
Been over a year I've been microsoft free now.
