how the heck it is going to be exotic for such a long time when there are 720p 4"-4.5" screens and 5" 1080p on its way with the cost of 30$(not retail).
they can force the market/customers to have those products for the price they want.
when apple/samsung/motorola/etc have 720p 640p 4" to 5" or similar screens on their phones, at the cost of 30$(not retail) you know that they can make a 12" combining 4 of those screens at the cost of 200$ with the proper circuits.
they could offer a 25" product with that resolution with a resonable price, but marketing has to do its tricks.
same thing goes on for the cpus also. the phones get a 25$ quad core arm, like that in sgs3, or the dual iphone 5 soc for the same price. a budget browsing and office pc would cost though 10 or 20 times more than that price. totally ridiculous marketing tricks.
