The only thing that matters is extensibility/customization and speed. I want the lightest, most customizable thing that isn't emacs (for real reasons, trying to set up emacs at work is too much of pain in the ass) as my single pane of glass on any OS I care to use. If it can't do that, it doesn't live long.

I want the lightest, most customizable thing, that is also Vim. Thank god there's Vim for that. (cloning my dotfiles for instant setup on a new box)
