The last meetings of the Programmers' SIG were about C#, and now it turns out you can develop iPad, iPhone and Android mobile apps with it. The tool is called Xamarin.
The "news" is that this new tool kit is available during August as a month-by-month subscription, so you can test this tool and its development evironment at pretty low cost. Company says you can cancel anytime and continue month-by-month indefinitely, even if the company withdraws this option.
