It’s fascinating to see the iterations a company like Apple goes through. These prototypes are clearly far more functional than some of the designs seen in the Samsung trial and meant to pin down the software rather than the hardware.
This prototype also partly confirms Steve Jobs’ comments that Apple had a working prototype of the iPad before the iPhone, and it was only when he started to use it that he suggested Apple make a phone.
Iterate, inspect and adapt. Very few successful products are birthed in their final form.
