I've been using Terminus for years. I've tried several times to get into "pretty" anti-aliased fonts, but nothing beats hard, sharp edges for a long day of programming. I specifically use Terminus with 16 pxlsize on a 15.6" 1920x1080 screen and find that delightful.

Coding with dark text on a white background is much easier on the eyes, too, unless you have a screen that won't let you turn down the brightness.

Pro tip: hold up a white sheet of paper in your well-lit work environment. Adjust your screen brightness to match the brightness of the piece of paper. Your screen should not be brighter than your work environment.

Super pro tip: work outside. Get a professional laptop with a matte screen, one of those lightweight "antigravity" chairs, and find a nice place to work outdoors. A 12x24" piece of wood makes a good lap desk if you need to use a mouse and fits well over the armrests of all of the outdoor chairs I have worked in.

I've been using Terminus for about six months and absolutely love it. Here are some screenshots from the homepage: http://terminus-font.sourceforge.net/shots.html

I always come back to Terminus. Been using it for god knows how many years now.
