I know this is nothing new but I thought it might be interesting to share my experience anyway...
I recently decided I would would continue to work on my DaMashupCode site on my day to day business machine. Also I decided I would work with Visual Web Developer 2005 instead of VS2005 Team Suite because I want to approach it how a non professional developer would.
One thing that doesn't work well on Vista is Visual Studio. Whenever I had built my project my code editor was all messed up. Now there is a fix out there. It (Visual Studio 2005 Service Pack 1 Update for Windows Vista Beta) is still in beta but you can download the here. Link was broken.

Also I'm using Expression Web trying to get some more CSS standard work into the site. The product has been released, you can download a trial here.
