In regards to 2 - I would bet that the tablet in his hands cost far in excess of $100,000 not $10,000 - or even higher, depending on how you account for engineering time. The raw materials won't cost that much, but building one-off prototypes is horribly expensive. Luckily they will amortize that cost over a million units or more so the cost of the first one is mostly irrelevant.
