Jen 23 December 2009 The great thing about this approach is that it let’s the css do the design and provides graceful fallbacks. Having sites render in an iPhone is easy if you’re using smart markup and style. For a real challenge, if you have the audience for it, have a site render usefully on a NON smartphone. That takes on an entirely different realm of coding expertise (far less fun, too). Yaili is exactly right. Spend less time creating exact experiences and more time moving forward.
