I've experimented with programming fonts and IDE color schemes plenty in the past. But now that I've given in to the inevitability of ClearType on large LCDs, I've basically settled on Consolas. It's hard to beat Consolas. It's darn close to the ultimate monospace programming font in my estimation. That's why I was so intrigued when I read about Inconsolata, a non-denominational OpenType relative of Consolas, which unlike Consolas, works equally well with ClearType enabled or disabled.
