I recently discovered for myself Consolas font. I didn't like it right away. However after 5 min of usage I fell in love with it. Just change default size from 10 to 11 points.
Consolas is a cleartype font designed specifically for to make code more readable is now available for download for users of Visual Studio 2005-2008 from the Microsoft Download Center.
Consolas is intended for use in programming environments and other circumstances where a monospaced font is specified. All characters have the same width, like old typewriters, making it a good choice for personal and business correspondence. Optimizing the font specifically for ClearType allowed a design with proportions closer to normal text than traditional monospaced fonts like Courier. This allows for more comfortable reading of extended text on-screen.
The package will change the default text face in Visual Studio to the Consolas family.
