I don't play games on computers as a rule so I don't want a GUI. I want performance for my world of bash+screen, or bash+screen+konsole+ratpoison, so I am unfamiliar with which distros have the best graphical customization of KDE. I used gnome in the 90's before Red Hat went all corporate challenger (keep it up!) to Microshotus.
Bash, screen/tmux, and ratpoison == productivity. For linux I still like the simple to customize, optimized archlinux. If I wanted to play games or watch TV, I'd use my xbox that I installed linux on (remove the hard-drive to manipulate directly and uhh you officially own the xbox).
I usually run a BSD as a matter of personal preference (I quite like the source
Which BSD do people use and what do you run on it? I've only been using OpenBSD for ssh/routing the past couple years, I used to enjoy the software available on FreeBSD quite a lot. I too enjoy compiling source, and have always admired BSD's amazing documentation for hackers (Berkeley!)
Backtrack is one of those tools IMHO that only comes around every couple years... what a supremely capable system. Backtrack is incredibly stacked when it comes to the tools, I always learn somethine new, wow. Knoppix has better hardware support though and I have used it for almost 10 years now, it was great wizardry by Klaus back then. Gparted is the recovery DVD I use the most often along with SpinRite (as cool as menuet).
