Had been on pop for a while. But lately gnome shell was using a ton of ram and performance was trash, so I moved to fedora with KDE. Been great so far.
I needed something lighter than windows 7 basic on a cheap network my girlfriend at the time (now wife) bought me when we were in high school. Ended up using Ubuntu 11.10 netbook edition. After spending 5 hours getting my Broadcom wireless card working, I was hooked. Used it until that laptop died and during that time I slowly migrated all of my computers to Linux. Only kept windows on secondary drives or a different partition for the occasional time I need it.
