Earlier quoted context omitted.
Java's value is not some inherent superiority of language for mobile development, it is about throwing (100s of) millions of dollars and 100s of engineers to make it work. And I think it remains true for C# also. Unless someone sinks 100s of millions on C# too it seems non-starter to me. By the way Microsoft has already tried mobile ecosystem with .net/C# that did not work out very well.
The transition from Java to C# is pretty easy and pleasant as C# is similar but better.
Oh really? Why?
