Having programmed in C, C++, C#, Java and JS (if scripting counts) I applaud this. I have tried to get used to Objective-C but after using C# for the past 4 years or so, it just seems uncomfortable with me (probably a personal bias that cannot be generalized). I was considering developing my startup's first mobile app in Android since I did not want to touch Objective-C and go with an iPhone Web Page.
Considering the number of developers on the .NET/C# bandwagon I think we will be seeing another Gold Rush to the app-store. I really hope the app-review board can filter out the ugly, form and buttons type of applications that will come as part of this rush. Otherwise, AppStore will be the next Tucows.
Keep in mind that using C# to program iOS apps is still very different than traditional .NET apps. The language is familiar, but the framework is definitely not.
I was a little disappointed to see that using Monotouch doesn't work my Visual Studio + ReSharper + nUnit development trifecta. C# as a language is nice, but the tools are where it's at.
