There's nothing quite like running your application through the debugger for the first time in a day after 6 hours of coding only to realize the shared dev SQL instance is stopped.  Actually it's quite graitifying to know that I'm making a web page flow change and haven't run a SQL query or fired up IE once all day.  Thankfully my unit test have been giving me good feedback all day long.

+1 point for unit tests.
+1 point for refactoring previously untestable legacy code.
-1 point for sharing the same dev database!  I can't wait to fix that.
