One reason I use Linux.
It continually surprises and impresses me, in a good way. As a little background: I’ve used Linux at a moderate to advanced level for a few years now: I’ve never written a bash script longer than 6 lines and never hacked the kernel, but I’m not afraid of the command line and have no problems editing my xorg.conf, grub.conf or any other system files using nano. The command line is my friend, but I still like a GUI admin panel sometimes.
