You may be right, at least in the US, public schools are very slow moving when it comes to new technology. However, the Raspberry Pi started as a cheap computer for schools as well, but has been very successful outside of that market, and I don't see why the same couldn't be true for these robots. Who wouldn't want a 10$ robot?
