I'm still using 7pt Dina, a monospace bitmap font, in all console windows and my IDEs - all except Visual Studio 2010, that is, which doesn't properly support bitmap fonts (leading me to avoid using it whenever possible).
I'm also a fan of Dina and it's been the first change I make to any IDE or programming text editor I use since I found it years ago. I recently came across this when I started using IntelliJ IDEA and needed a TTF font: http://chrisrickard.blogspot.com/2010/03/dina-font-for-visua... . Quote from the page:
*bonus* I found that this font can also be used with any .NET application
(WPF or Windows Forms) that normally can't handle raster fonts.
I too use Dina (based of Proggy). I tried a lot of different fonts and there's a few on this top 10 list that wouldn't work for me but since I found Dina, I haven't searched for another font or made another change.
