>I kind of get the impression that a lot of their sales went to the uber-geek crowd What's wrong with that? Why does a teaching tool need to be a near-useless way too expensive hunk of shit that nobody would want because it has no utility outside a narrow range? I've incorporated the Rpi into a course. The only thing inconvenient about its popularity is that they are sometimes out of stock. But, on the other hand, its sales volume probably helps keep the cost low; and the popularity means that there are many fun examples, and lots of free help developing curriculum and tutoring students.
