I have seen a number of questions here on SO about the differences between Xamarin and Titanium and PhoneGap, and they got tons of upvotes, so I believe this sort of comparison question to be on-topic. I am looking for facts, rather than opinions.
I'd like a comparison of Adobe FlashBuilder, Telerik AppBuilder, and Intel's mobile SDK (formerly appMobi), especially on the following points:
-- is a separate runtime needed on the mobile device or a single package?
-- is cross-compilation a possibility, to produce native binaries?
-- how are styles applied?
-- what about support for media queries?
-- relative performance
-- stability/robustness
-- debugging
-- IDE
-- any additional hardware required to produce iPhone apps?
-- market share/installed base
