this seems rather pessimistic; while the initial run is 10,000 units, they have said things like "We have a very low fixed-cost base, and will break even when we reach sales of 20-30k units per year," which imply to me they have much higher goals than just the first run. And unlike many of the open source efforts around things like this in the past, it's being produced by experienced engineers with close ties to a large electronics corporation. Calling them "a non-profit from the UK focused on education" is pretty misleading. To even consider selling to the government via the education system suggests they're ready for serious scale.
