This is a hot topic indeed, and something I hold very close to my heart!

Per my fledgling blog post at http://archieeddison.wordpress.com/2011/04/02/mobile-phone-apps-are-dying/ I think HTML5 and web apps are going to become more the norm, and more rich functionality and new features will fill more gaps in due course. As you may not have expressed in your article, the target audience is actually probably the widest you'd ever have when developing for the web. Develop it once, develop it well, and the world could well be your oyster!
