I agree but....
... you have to take in account that this changes amongst social stages.
At the very beginning, cars were something that only high society could afford.
Today, iPhone, iPads and iAnything require high amounts of iMoney but are the dream of everyone. The acquisition power of customers will change along with the technology cost, but this technology will still be the dream of a lot of people.
(And I'm not going to talk about the real cost of any tablet, where factories sell them with prices starting at USD 50 or less).
