I'm quite new to linux, like 6 months old.
What pushed me to linux is windows 8, plain and simple. I was "beta testing" it since december 2011 and first I liked it, but then it grew sour on me and 6 months later, when I tried to push the charms bar back in it's pit while I just wanted to use the scroll bar one time too often, i got angry. I mean more than usual, and I browsed for a linux distribution. I saw ubuntu (which I did try some years ago without much success), and I didn't like either printscreen or the fuss about unity. I stumbled on a mint printscreens, and I was sold.
1 hour later I was using mint 13 Cinnamon, and I was blown away. This thing looks nice, and unlike past experiences, it installed without much fuss. But what struck me most is that, after a couple hours of normal use, I felt calm, zen. It was like I was in japanese bamboo garden on the foot of a mountain, birds singing around, a nice cup of hot strange tea in my hands. Or at least in my head. I didn't shout once at my computer, and didn't sigh in frustration 10 time per hour anymore. I realized then I was not stressed out by fear of going in the metro menu, or activating that dreaded charms bar. Mint is not going against me, pestering me, I can concentrate on what I do best (watching youtube videos
The only thing I miss from windows is total commander, cause I used it since 1997. I don't miss games, since my last windows games were supreme commander 1 and modern warfare 1. And things like node, eclipse, sublimetext integrates more smoothly on linux.
Until wiindows 8, I was kept at bay by missing drivers, or more like the fear of them. But now I took the plunge, I definitely like the waters I dwelling in, and there is no way I'm going back.
