I don't know about the numbers on it, but as far as I'm aware, .NET is quite successful. While the original release was fairly poor and highly derivative of the Java world, they've done an incredible job from .NET 2 and up. With each release, they've made the framework more useful, they've improved their languages (I'm not a fan, but C# has come a long way), and MSR has been doing awesome work on the research side of things. There are a lot of negative things you can say about .NET, but I don't think a lack of innovation is one of them.
