TI, CSR, Broadcom, etc have tiny chips which provide multiple rf technologies (wifi, gps, bluetooth, fm radio) in one. I don't know prices, but if the total for a prototype was pushed up to $75 it would still be much cheaper than other alternatives and still within range to replace my phone.

Increasing the cost seems detrimental to their primary goal:

"We plan to develop, manufacture and distribute an ultra-low-cost computer, for use in teaching computer programming to children. We expect this computer to have many other applications both in the developed and the developing world.

Our first product is about the size of a credit card, and is designed to plug into a TV or be combined with a touch screen for a low cost tablet. The expected price is $25 for a fully-configured system."

Check out the BeagleBoard or Bug Labs, they do basically those things and cost >$100 each.
