OLPC XO-2 - At Last, A All-round Functional PC?

This is a way cool new PC concept. The size of a large hardback book, but a quarter of the width; two touch-sensitive, haptic-enhanced screens that can function as a key board and a monitor, when opened like a book, like two screens, when laid out flat like two touch screen tablets. What more can you ask for? And for a target price of $75?! Sheesh.
