BYOD can be a problem when it take two months to fix a Chromebook under manufacturers warranty (rather than paid for extended warranty).
I have a student who has been waiting two months for a repair by Noel Leeming (or so I am told). In the meantime she has no device to use at school and has to resort to text books. I suspect she is getting behind as a consequence. Should the school have a “hire” scheme for devices?
