@Erika Meyer: I agree with you. Perhaps the demos should have resulted in a different experience for iPhone users (via media type, sure). I intended the demo page to simply illustrate the idea of test-driven enhancement in a way that seemed somewhat easy to follow. How a site will actually implement their enhancements across devices is left to the developer and the test cases they choose to include. Thanks for your insight, though. As I’d said earlier, one might decide that iPhone users would be better off using select menus, particularly due to the nice native wheel interface that iPhone provides!
