First class MS languages fit into the entire "environment" in a way that the less important ones can't even begin to approach. There are a bunch of super interesting languages that are extremely tedious to use in a mixed language .NET environment. Things like MS Build support, VS integration, and everything else are really nice to have.

Even F# suffered before MS really bought into it. It had basic VS integration, but no MS Build support, and other quirks that just became a headache to deal with every day. With the CTP, I can add an F# project to an existing .NET solution and use it like I would C# or VB. It's saved me a ton of time already.

As to why you want more: I want more because it's good for my brain. :) I also want more because I can attack problems with a tool that may be better for the job without breaking out of my applications.
