WOW, let me hear that again: WOW!!!
In short. I started dual-booting in 2004 and switched to linux full time in 2005. This means that I have been using GNU/linux for two decades!!!
The word "exclusively" is used for emphasis, since I have also been playing and using other operating systems. Mainly BSD and occasionally Solaris (or some sort of derivative).
But somehow I always come back to debian, do not ask me why. Call it what you want, maybe because I am too used to it or who knows. Maybe it is just love at first sight (which is very likely)
Keep on rockin'
