Here is a nice enumeration and previews of fonts for programmers (via Roy Osherove and Bradbury Software Forum). My favorite was Bitstream Vera Sans Mono (download) which looks a bit thin and sparse but crisp enough. Anonymous preview looked nice too but ended up looking too thin in ClearType. So I am going to give Bitstream Vera Sans Mono a spin in both VS.NET 2005 and Eclipse.

The font I really want is Consolas which will ship with Longhorn. Rest of Longhorn fonts look great as well. Yummy. Too bad I don't have time to play with Longhorn prelease bits.
