The XO-1.75 prototypes are currently under development, and the laptops will enter mass production this summer. Some touchscreen prototypes are being made as well, but the primary model will not have touch. Thanks to Armada 610 ARM processors and improved Pixel Qi screens, the 1.75 will draw roughly half the power of the 1.5, while keeping roughly the same form factor and most of the existing industrial design.
These will be our first models with ARM chips, which we plan to use in our tablet designs later this year. The 1.75 should be roughly $20 cheaper to manufacture, than the 1.5, but the real drop in cost will come for rural deployments, as a result of the lessened power requirements. Not quite in the human-powerable range yet, but getting there.
The XO-3 will have a larger 9.7″ screen when it comes out in 2012, and will shave off another significant fraction of power – up to another full Watt.

The post mentions that the screen size will be larger. What will be the exact size of the XO-3 screen?
