I use terminal based Vim exclusively and now I'm completely spoiled. Every other interface seems ridiculously "laggy". I don't know if it's just a psychological thing or something more like the SpeechJammer, but if I type at a co-workers computer I will sometimes completely lock up and be unable to type for a second or two.

I really don't think that is a psychological thing, i ben using emacs in the terminal for years and only within Apples default Terminal application because iTerm is really laggy on linux i prefer terminology that is really really fast

+1 for terminology. Fast even on the cubieboard that I (also) run it under, and somehow, in my opinion, it does font spacing really well even under Ubuntu. Better than the standard terminal in both Unity and (especially) Gnome where kerning can be weird even on mono font.

No framebuffer, right? In my experience, the framebuffer introduces an annoying and noticeable delay.
