Yes - I ran a trial a while back to see just how difficult it would be to get a common HTML/CSS/JavaScript set to work across iOS and Android browser variants for a non trivial graphical app. [It was quite difficult - much simpler to write 2 variants - but that was why I ran the trial]. Using PhoneGap the trial app is doing well as a free download in the Google Play Store and the Apple AppStore.
