Yep - Vim, working on python code. It's pretty darn good. The terminal occasionally gets confused when you're popping in and out of an alternate-screen app (less or vim) and leaves the bottom line of the alt screen behind - but this can be fixed by hitting ctrl-L. Also the terminal occasionally seems to report the wrong size and vim pops up only using some of the available space - again, suspend vim, ctrl-L, unsuspend, done.
