With the success of the XO laptop from OLPC, it makes sense to start working on a second generation device called the XO 2.0. It will be much smaller compared to the first one, and will feature a foldable e-book factor.
It will also be just half the original’s size, with dual indoor-and-sunlight displays that provide both a right and left page when held vertically, a hinged laptop in horizontal format as well as a flat, dual screen continuous interface for tablet mode. Power suckage has been reduced to just an impressive 1 watt. You’ll have a nice long wait though, since it will be released sometime in 2010.
