ProFont - nice font for VS.NET
Old news from Joel on Software that I finally got around to playing with: 
It's a fixed width font that looks good at small font sizes, slashes zeros, etc.:
Back in the days when I did Mac development (System 6) the biggest monitors available for the Mac were maybe 9", and the only way to see a reasonable amount of code on screen was to use a tiny font. Now that I have two 18" LCD panels, the only way to see a reasonable amount of code on screen is to use a tiny font. The world is awash in lovely TrueType fonts but none of them are monospaced, which is a nuisance for programming because things which should line up won't.
Fortunately, I have found ProFont, and all is well again. For best results use the FON version, not the TTF version.

Well, I've been using it as my default font in notepad and Visual Studio for a week and I'm still happy with it. The TTF version seems to work best for me.
