TFS is more than version control. It will run your continuous integration, tracks bugs, work items, story points, etc. It's useful for team collaboration. If you aren't doing much team collaboration, then some of these other pieces aren't useful for you. However, even in small shops you can see big wins from bug tracking and continuous integration.
>I'm perfectly capable of checking in/checking out source code without having to have it integrated into my IDE. I really haven't found anything else that TFS is good for.
