The following article from Smashing Magazine speaks to the benefits of building sites using HTML5 bit.ly/ehRmEd. Two key points are made. First, start simple and then scale up. That is to say, design for the most simplistic mobile interface that you expect users to interact with your site through and use this as your base. From this starting point you can then sclae up to a more complex desktop design.The second key point the article appears to make is that designing mobile websites for on-the-go browsing may make more sense that designing multiple apps for multiple mobile platforms (iOS, Android, RIM, Windows 7). Ultimately, I think designing an app-like experience using HTML5 is the way to go, but at present app-focused mobile interfaces still seem to be the preference. In any case, this article is worth a read.
