I attended a VSTS 2008 seminar as part of the .NET User Group. First let me say the speaker, Chris Menegay from Notion Solutions, was great.There were some things that I really liked

• Check-ins, work items, and builds were all tied together automatically

That takes significant effort if you are doing it yourself. I have at various times and for various companies built these systems from scratch, and it is a *lot* of work.

• Shelve

The ability to store a set of changes and go back to them later is nice

• Ability to add Check-in policies

Like associate with work item, code reviewer required

• Data Generation Plans

These freaking rock, ’nuff said

There were also some things I didn’t like

• Would be nice if there were a better pricing model for the independent (very) small businesses.
• No Windows explorer integration for source control
