[From Jeff P] Microsoft marketing got it all wrong with VS 2005
The first is that the entire Visual Studio product line has been fragmented to death. The differences between standard and pro are silly enough, but the Team System skus are even more ridiculous. Collaboration my ass. Whether it has been in a small team of two or in a giant corporation, I've always had to have all of the tools on my computer to get the job done. That includes requirement management, defect tracking software, testing software, quality tools, Visio, Office, the IDE itself, etc. The arrangment of the VS skus pretends that we all live in these discreet little spheres and never cross into other areas, especially the VSTS products. What a shame.
