We recently upgraded to Visual Studio 2010 Ultimate and I had some free training time, so I dove into the database project stuff. At first, I thought I was wasting my time, but like Jamie said, it all started to "click" at a certain point, and you get it. And, it's pretty awesome what you can do, especially with the refactoring of columns - automatically changing all the objects that reference that column, having each object as it's own file (yes, 1000 per folder limit due to performance, heh). What can take me hours on end happened in 2 minutes with this tool. Seriously.
