I don't know if this is it, but at some point in the next 5 years a super-cheap tablet like this one will change the world.

The specs seem pretty good:

The new Aakash 2 tablet comes engineered with a 1GHz Cortex A8 processor, while the original Aaaksh tablet was powered by a 366 MHz processor. The Aakash 2 tablet has a a 7-inch capacitive display with four multi-touch points. The screen has a resolution of 800×480 pixels.

Aakash's last tablet was a flop. Fingers crossed that this one does better.

Absolutely.
