As a former k-12 edtech practitioner-- these are terrible as a CB replacement. There are 6 reasons the CB has market dominance 1. dirt cheap 2. cattle not pets 3. manageable 4. google apps integration 5. available in pretty rugged form factors 6. pretty boring, not an attractive nuisance for poking and prodding these things run windows, which in and of itself gives substantially more nooks and crannies to poke at. the hardware is all modular and accessible and losable from a technology education perspective, these look amazing. but the majority of technology in education is and should be about as interesting as a pencil.
