Your all dumb!
I cant beleave how many people are moaning about cranking while its attached to your face YOU DONT as long as you have spent some time winding it before hand! DOH!
The whole interview was really bad actually, people talking about things they don't have a clue about, even the company representative. Both of them were grasping for an understanding.
I would presume what the developers have not just smacked a standard phone inside with the gizmo, I would have hoped they went for all ultra low power options. The screen must take up loads of power, selecting the most power efficient screen had to be number one! Along with managed charging of the battery via the gizmo.
It looks big and clunky, they could add a bit of rubber around the outside and make it splash proof or better still waterproof and then it really is setup for the harsh conditions of life without mains. A phone for backpacking! Africa etc! Leave it in the sun to charge. Its a good idea, stick a GPS in it! With a manual on/off switch so you don't drain the battery looking for the software OFF options for the GPS. Perfect!
