Surprising new data on mobile application development

The folks over at VisionMobile have updated their Developer Economics survey with some interesting changes since last year in mobile application development trends and plans. Herewith are a few nuggets:

• 84% of mobile developers use iOS, Android, or HTML5 as their main platform; only 4.5% are targeting Windows Phone.
• Even though Android has 4x as many shipping devices than iOS, developers use iOS as their main development platform over Android by 59% to 49%.
• Although when you ask developers what they are GOING to target, over 40% say Windows Phone; in reality only 21.5% use it as their primary dev platform.
• It's not the programming language that's a barrier to adoption, it's the API. 
• 1 in 5 devs are either currently targeting or plan to target TVs; 93% currently target smartphones and 70% now target tablets.
• If you're a little bewildered by the plethora of frameworks, platforms, and tools that have sprung up to help you do mobile development, you're not alone: over 200 different startups in the space have emerged since 2009.
• The smart money in the Yukon gold rush stayed in Seattle and sold eggs and shovels to the would-be miners headed north. In this gold rush the equivalent items are user analytics and cross-platform tools.
• 61% of HTML5 developers target the browser (either a web app or mobile website) while only 27% so far are developing hybrid (ie using PhoneGap or similar) apps. This makes sense when you consider that the vast majority of mobile developers are primarily focused on the consumer marketplace.
