you know that recent quake demo on that creditcard sized pc?
well... this is a 23 year old talking, and i despise smartphones, phones, and in general, any tech that is realy a step backwards.
but the screens on these things cost how much to make? 30-50$
the pc credit card thing will cost how much? 25-35$
a simple touch screen that requires pressure costs how much to implement?
and lets throw in a 3mp camera and a small web cam for the hell of it.
lets say all this, and a battery that lasts, i don't know, 2 hours unplugged, but came with a car adapter, and a charger, and an external battery system
im pretty sure the price of said machine would probably be under 100$ for a 4ich screen, and probably about 150 for a 10 inch tablet.
you could sell them for a base price of probably 120$ for the 4 inch, and 150-200 for the tablet size, and still pull in proffit.
make your own os, and make it low profile, and there you go. a device that is a guaranteed win.
