== Emacs but not vim? == 

 I think it's a pretty questionable choice to include emacs, especially instead of vim. Look at the statistics from Debian's Popularity Contest to see why I think that: 

 http://qa.debian.org/popcon.php?package=emacs23 
 http://qa.debian.org/popcon.php?package=vim 

 If someone can show me some data that suggest emacs is more widely used than vim, I'll gladly let it go. However, I think including a text editor here is arbitrary anyway, since managing "windows" (meaning individual applications) in the traditional sense isn't an editor's job. It would make more sense to me to include a terminal multiplexor like screen or tmux as opposed to an editor.
