So my takeaway is that he prefers using Visual Studio and C# to write mobile applications, followed by java/eclipse/emacs for the android and Xcode/ObjC bringing up the rear.

I think its a fair assessment, as someone who spends his daytime hours in VS2010 writing C#, the tools are first rate. I personally like objective C as a language(I think C# and .NET is growing at a rate that will tire of keeping up with before too long where objective C is lean and easy to learn), and feel that things could be better if XCode were better. That said, the iPhone simulator is at least 100 fold better than the WP7 emulator.
