I'd pay top $$$ if someone could show me how to let a mobile Safari user record audio on their microphone and submit it. iOS doesn't permit this in any way, whether it be with getUserMedia or media capture forms. The only way to do audio recording is to build an iOS app just so I can get this one simple feature which is exactly what they want. Repeat this story for a dozen other features as well.

Apple's total opaqueness on what their plans are for the future functionality of their browser certainly doesn't help either.
