A former Apple employee, whose name appears on numerous Apple patents, worked on an Apple tablet five years ago and recently told me when the first version of the tablet was shelved by Steve Jobs, a lot of the technology made it into other devices. He explained that components of these early stage concepts are already out in the marketplace. If you have an iPhone, for example, you’re carrying around a mini version of an early Apple tablet. He also says that one of the barriers to producing the early tablets was the lack of software. The success of the App Store and the eagerness of the publishers show that this won’t be a problem for any new devices.
