Who needs a desktop environment anyways? ;)

I just run xmonad and dmenu, plus xmobar for convenience (shows me the time and cpu/memory/net usage). Win+p launches any app on my path, Win+shift+enter opens a terminal. I use the same setup on all my machines and don't think I've spent more than a day in total tweaking my config over the last 5 years. It just works.

The only reason I'd buy another mac is for the touchpad.
