There is some information about the OLPC project of Nicholas Negroponte. Apparently the 2nd generation OLPC XO laptop will only be a hardware upgrade of the current model and OLPC focuses on a completely new design for the 3rd generation which is supposed to hit the market in 2012.
Negroponte is quoted in an article on Xconomy as saying that the XO 3.0 is a single sheet, completely plastic and unbreakable, waterproof, 1/4" thick, full color, reflective and transmissive, no bezel, no holes. 1W and a price of $75.
As always these are pretty impressive goals to achieve.
2012 is only 2 years away. If we look at the state eBook readers are in and how expensive they are than I am not sure if the OLPC will achieve the above specs by then. The photo above shows the dual screen concept for the XO-2 that appeared in 2008.
