I don’t think it’ll be a hard sell for schools at that price, school budgets tend to be fairly elastic for new things (and sometimes for wholly unnecessary things, for the price of less than 1/4th of new MacBook for the principal (for example) they could have this.

Edit: also if schools were to be interested in this (which they should be, it’s very neat) they could group together and buy in bulk which would also greatly reduce the price
