The concept of “One Web” is not a lie, but it is optimistic.
HTML5 can mask the ‘bring your own device (BYOD) dilemma,’ but fundamentally there is a time when you have to optimize for the device. However, as you design you should look for the places where a device can add to the mix of responses.
Dave Kaneda suggested that reading all the design guides from the device OS companies would be a good place to start when looking for what should be done in common and what should be done to optimize. With that knowledge and the use, Unity, JQuery and PhoneGap are tools that help to manage the common.

Remember you may think your app is Intuitive, but the user is trained by their device and the Web. To the see the presentations from DevCon5 visit the site here.
Good Luck and Good Coding.
