For t3h freedomz.
I started running Linux because my Windows Vista box was so sloooooooooooow. Someone suggested that I try Linux, and for about six months I dual booted. After wiping Windows on that machine, I never looked back. Do I still use Windows? Yes, on my work machine, but even my Windows experience has gotten better because of the knowledge that I have gained by using Linux. Just using Linux has opened my eyes to a ton of possibilities. (All of that being said, I still get VERY frustrated waiting on my Windows box to do something that #! would have done in half of the time.)
Why Crunchbang? Well, here was my progression. Linux Mint - Linux Mint Debian Edition - Linux Mint XFCE - Debian XFCE - #! XFCE - #! XFCE with added Fluxbox WM - #! OB. With #! OB I have found my preferred balance between usability and lightweight.
