I honestly don't see how this is gong to encourage people, especially kids, to further wonder about how computers work, and what actually happens. It's smaller, and if anything even less accessible than a desktop machine.

I learned about computers and computing by building my own from a Z80, 8KB RAM, 8KB ROM, random logic, etching my own circuit board and soldering the components and sockets in place.

Should kids do that these days? Would it help?
