I think the release of the iPhone SDK will be the first step toward Apple moving toward a complete revision of Mac OS that seizes on the simplicity of iPhone's OS to overhaul the way we view the Mac. There's no reason why I would not want an iPhone OS-based appliance of some kind today outfitted with iWork, iLife, Mail and Safari. Such a device would return the platform to the point, click and explore simplicity that made System 6 so great while embracing advances in hardware and software technology that allow us to break the icon/menu pointer paradigm. The SDK provides the foundation for other major software developers to start down the path of creating simple, but powerful applications that function using new paradigms that only the iPhone OS allows. While I know a lot of people wouldn't like it, I think consumer also would like the idea of an iTunes-like experience when shopping for and installing new apps, games and widgets. The current system is too convoluted, too difficult for mass-market consumers to "discover" and try new apps and too open to trojans and other security threats. Perhaps OS XI could open an iTunes-like distribution system that allowed developers simplified ways getting their apps to customers and keeping those apps updated with the latest bug fixes and features. Your thoughts?
