I actually heard Eben Upton present an inspiring vision of affordable single board computers for both home and classroom education and experimentation. He seemed sincere, and the evidence seemed to back him up. That's probably a part of why it felt like a bait-and-switch when they pivoted to business sales. In retrospect it was probably a mistake for anyone to design a course assuming availability of Raspberry Pi boards without a readily available alternative board. Perhaps some relevant lessons are: 1) Businesses, however inspiring their pitch, are strongly motivated by money; customer support is proportional to the amount of money they expect to receive from you in the future 2) Always have second sources and backup plans
