Ironically, it was speed that was a major sticking point.  There were 
about three editors out of everything I tested with the screen/input 
response to satisfy me.  I'm not talking about things that take actual 
time, like search/replace etc., but regular things like scrolling or 
pageup/down.  I understand some of these have legacy terminal roots, but 
  80x25 is only 4000 bytes of memory, it shouldn't be rocket science to 
update it in a timely fashion... unless your text is represented 
internally significantly more complex than structures of strings I suppose.
