Generally speaking - most of the monospace fonts I see are totally fine and I really don't care about the differences between the 10 he mentioned as being good. But when I go to windows and run cmd.exe I'm blown away by just how ugly the font they use there is.
You can actually add more fonts, though it requires editing the registry and doesn't work for all fonts, I think. It does let you at least get Consolas, which is good enough for the time I spend in cmd.
