Targeting/Developing for multiple mobile platforms with one programming language (C#)? Cost-Benefit?

Question

Today it is possible to use C# programming for multiple mobile platforms such as:

• WindowPhone7
• Android - Monodroid
• iPhone - Monotouch

Answer 1

a big advantage is certainly the reusability of code / class libraries across the platforms. With that in mind you`re able to port/develop applications even faster, which in turn reduces the costs.

Also, because of the reusability of code, it will reduce maintenance expenses.

Answer 2

Another way to look at this is you could port an existing .NET/C# application to a variety of mobile clients (both native and non-native) relatively easy using WebORB integration server. On the client side you would have to code in either the native language or you could create an Adobe AIR application that is fairly portable across different mobile OS' such as iOS, Android and BlackBerry PlayBook.
