From my experience in marketing technology devices, the price of any tech device depends on the cost incurred by the customer due to the problem the device is trying to solve, and also the other alternatives available in the market. That the tech device is able to solve the problem is of utmost importance, and not the price.
The best example is the Akash tablet. At 2500-3500 rupees you have a really clumsy device which does not solve anyone's problems. Instead, at 6500- 9000 rupees you have various tablets, including the micromax funbook, which address the customer's need to have a handy device with which to browse the internet. One would rather pay a little more and have something which works, rather than save a little and end up with something which is useless.
