Jeff is pimps his IDE so I thought I would show mine off.  Nothing special but not ordinary either.

Here is the rationale behind my decisions:

• I changed the font to Proggy Clean.  It is cleaner but sometimes I switch back to trusty Courier New.
• The background is 234/235/220.  It's easier on the eyes than bright white and provides a good contrast to the text colors.
• Like Jeff, I highlight the strings so I can see them but I do rely on the quote matching feature of ReSharper too.
• I changed fields to Maroon from ReSharper default of purple.  I didn't like having that much purple.

That's about it I think.  The other colors there are all defaults of VS.NET 2003 or ReSharper.
