Came across this interesting article on InfoQ about a survey on the adoption of various cross-platform tools by the developers. PhoneGap and Sencha Touch seem to be the top two tools actively used by developers. At the same time, PhoneGap doesn’t seem to be really a favourite tool.
It’s also not surprising to find people wanting to move away from Flex.
One cannot jump to any conclusions based on this survey but definitely interesting to read.
