Here is a great presentation by Scott Hanselman demonstrating MVC 1.0 and how he created NerdDinner.com with it.  He talks about the nuts and bolts of MVC, but also talk a bit about how MVC lends itself to support different roles within an engineering organization.  Service developers only need to worry about the Service Layer and UI developers only needs to worry about the Presentation Layer.  MVC is great at separation of concerns.  Sit back and relax, its a long video, but well worth it.
