I use Outlook 2013 every day. I don't agree with the styling, but it does more color than Visual Studio. White, Light Grey, and Dark Grey. Granted, software doesn't need to look like grandma's patchwork quilt, but god, it's ugly.
As much as I want to use SSDT and VS 2012, it is so hard on the eyes. I've actually done community demos in 2010.
Sometimes on this topic I channel Bob Uecker in his Major Leagues II movie, when the pitcher issues a surprise unintentional walk, and Uecker says, "obviously, the manager is thinking....well....I don't know what the hell he's thinking!!!"
