I'm not sure. Depends on if you count the iPod, iPhone, and iPad as 1 or 3 products. the 2006 iPod seemed very different from the 2007 iPhone. To my mind, those are different things. I can see the desire to blur the iPhone and iPad, it's just a change in form factor. Thinking back, not many people thought tablets would take off. They seemed sorta like 3d tv.
