While One Laptop Per Child project's goal of improving child education in developing countries can only be characterized as a noble one, the so-called $100 XO notebook itself hasn't exactly been a huge success. That's not stopping Nicholas Negroponte from touting a second generation XO cheap sub-notebook though.
Version 2.0 of the XO will use two touch screens that adapt to a given context, providing a right and left page in vertical format, a hinged laptop in horizontal format, and a flat, two-screen continuous surface for use in tablet mode. It will also be about half the size of its older brother, and reduce its power consumption to less than one watt.
The revamped notebook is far from production, being scheduled to launch in 2010 with a target price of $75. Given the OLPC's difficulties in meeting its ambitious goals with the first XO, though, I have to admit I'm a little skeptical about the nonprofit's claims regarding the XO-2.
