I'm currently writing a project using Xamarin ( http://xamarin.com/ ). Did the Objective-C thing at a previous job for about 6 months. C# is way way better than Objective-C, and you get the added bonus of being able to reuse your business logic (and even some of your UI depending on how you write it) across platforms. There is some overhead in learning the apis through C# instead of Obj-C, but its more than made up for by a better language and cross-platform reuse of code. Not as many examples of how to use apis in C#, but, for the most part, its pretty trivial to translate things from Obj-C. The worst bit is that existing third-party libraries are substantially harder to use. You do have to pay for a license for apps over a certain size, but its only $25/mo for an indy developer.

I know I'm going to look foolish for saying this, but I actually watched part of the video (enough to know how apple products are portrayed)! The apple product in the video is being used to file for a patent. There is _nothing_ in the video about patents owned by apple, or patents involving apple products. The suggestion by Samsung that the video biases jurors is absurd.
