I have only just tripped across the procedure for adding new fonts to the list of those that you can set for the windows console (command prompt). Scott Hanselman mentions the process in a June 2005 post on his blog, and links to a Microsoft KB article.
I had been a steadfast user of the Bitstream Vera Sans Mono, but I think Consolas looks better. Consolas is installed on my Vista system with Office 2007, and Outlook 2007 uses it as the default font for plain-text formatted mail.
