I do like the look of Consolas or Inconsolata, but they don't fill the
screen in ACS--at least not for me. The characters are too short and I end
up with dead space (large blank areas) at the top and bottom of the
screen. For me, Monaco fills the screen quite nicely while looking fairly
crisp. If I could find a Consolas derivative with taller characters, I
would switch in a heartbeat.
