I'm doing almost exclusive ASP.Net MVC work now. It's a great platform. Easy to use. Easy to test due to separation of concerns. Your issues with Silverlight are valid, but both MVC and EF have been open sourced by Microsoft.

The advantages we would see in using Asp MVC would be to have a programmer friendly development tool (VS) which goes well along with the development of the host application, which also would be done in VS using C#.
