This is why Intel is becoming irrelevant in the embedded space.
While I am sure that this is not meant as a raspberry pi killer, the lack of a low cost Intel platform means that all cool interesting stuff is being done on ARM.
Not only that but the next generation of embedded engineers will grow up knowing about the ARM architecture, and Intel will become increasingly marginalized.
If I was Intel I would produce a $30 board, put on a version of vxworks linux (also Intel owned) and give them out to schools at the same time encourage the hacking community to extend the boards. But it won't happen, because Intel cannot see beyond PC's which are increasingly becoming irrelevant in the modern world
