>>>Hi,
>>>
>>>If anybody done any work or some research of developing a business application for iPad, I have a question. I have two options (at least I can't think of others now): 1. Using MonoTouch from Xamarin develop a native iOs/mobile application or 2. using HTML5 with ASP.NET creating a web application. Which approach would you recommend? TIA.
>>
>>I thought the iPhone/iPad/iOS is a closed platform (?) In that case, wouldn't it make sense to use Apple's recommended platform? http://developer.apple.com/ipad/sdk/

>I have not looked in details at the "recommended platform" but I think it is probably designed to use ObjectiveC as the language. This is totally new. The HTML5 with ASP.NET and/or MonoTouch from Xamarin allow to use C#.

Ah, you didn't specify that. There is more info at http://stackoverflow.com/questions/4663870/appcelerator-vs-monotouch-which-one-is-best-for-a-net-developer .
