Why, Microsoft? Why?

While flipping through a new set of MSDN DVDs that arrived in the mail today, I came across one labeled Visual Studio Team System 2008 Team Foundation Server Workgroup. Having absolutely no idea what any of those words meant when used in conjunction with one another, I looked up the product. Here's what Microsoft has to say:

Microsoft Visual Studio Team System 2008 is an integrated Application Life-cycle Management (ALM) solution comprising tools, processes, and guidance to help everyone on the team improve their skills and work more effectively together.

Wow, sounds nice, doesn't it? I want to improve my skills, and there's nothing wrong with working more effectively together. However, on a practical level, I STILL HAVE ABSOLUTELY NO IDEA WHAT THIS PRODUCT IS OR DOES.
