Work is already underway on the “XO-2″ laptop, which will be cheaper and smaller and will use less power. The XO-2 comes with Nintendo DS-like dual-touchscreen displays, which can be customized for different aged children, different applications or different languages.

The current purchase price for the XO laptop is $188, but the OLPC is hoping that it should be able to reduce the price per laptop below the $100 target and it may be possible to achieve a price of $75.

The XO-2 should be available in 2010, but there are reports from info Sync World of an interim XO-1.5 which will be released in the spring of 2009 with the same design as the first generation but with fewer physical parts and at lower cost than the XO 1.0.
