"75 percent of applications are already designed in HTML5, with an overlay to fit smartphones from Apple or Google." I'd really like a source for this. He seems to be saying that 75% of apps on the App Store and Google Play are HTML with a thin wrapper – the PhoneGap model. This doesn't match the top apps on either store, they're overwhelmingly native code. Is there some kind of a long tail of HTML5 apps out there? Does Mozilla count every app that uses some kind of a web view? Or did they just make the number up?
