I said this in another comment, but I think the interesting aspect here is that this will be a gateway-to-computing device, just like the BBC Micro was of its time.

Sure, its not comparable in terms of richness or depth of a machine to the Micro, but then all schools have PCs now. Its just they're used for Office and learning how to be safe online. Not for coding.

Let's hope kids then start asking their teachers how to do more than blink some lights, and ask their teachers to learn how to build websites, apps etc. Then it'll be a success.
