I'm a little bit obsessive about my computer's performance. To some extent, it's weak (well, a midrange laptop). To some extent, I do a lot with it (programming, remote file management, internet, development). But mostly I like making the computer get out of my way so I can work.
Until recently, I was using XFCE. It's a wonderful desktop environment, with nice integration - all of its applications play nicely together. Earthbound (my laptop) boots to a commandline login. After I enter my credentials, .bash_profile runs startx, which starts XFCE. It works well, except that Earthbound takes fully ten seconds to start X and all the tray applications. I wanted faster. (And yes, I know I'm being absurd.)
