Chris and I were on iDeveloperTV's podcast #59 last night, talking with Scotty about MonoTouch. It's normally a very Objective-C-focused show, but I think we managed a very balanced discussions about when MonoTouch/MonoForAndroid etc are useful for iOS developers.
Scotty talks with Chris Hardy from Xamarin and Nic Wise from Big Ted about MonoTouch an iOS layer on top of the opensource .NET clone Mono.
