I don't understand how come that Indie license does not include Visual Studio support? I think the biggest issue with Xamarin for me is this: http://i.imgur.com/wmdaLL7.png
I agree. Xamarin has a price difference between "Business" and "Enterprise" but really the 600 bucks for Visual Studio support is what differentiates between Enterprise vs everything else.
I wonder if Visual Studio starting to integrate Phone Gap tooling could eat away at part of Xamarin's value proposition.
Regardless what Xamarin does with pricing, their announcement today with the new native UI builder is huge, congrats to the team.
