The XO-3 design work is coming along, still scheduled for the end of next year. The screen will be one of the latest Pixel Qi models. They will run Linux, though what flavor is still under investigation; followers of C. Scott’s blog can read the full details there. And like the XO-1.75, they will use an ARM chip.
In an IDG interview, Nicholas notes that design discussions about how to implement solar and satellite connectivity continue. Meanwhile, those interested in working on software for the XO-3 are invited to get involved in XO-1.75 hacking this summer.
Contributors program versions of the beta-test boards will be available soon.
