Re: why is it your problem?
Yup.Plenty of classrooms with non-working smartboards because the Devils Brew of connecting a laptop, smartboard, projector, speakers, network and assorted sockets is just made to be high maintenance and education doesn't have funding for maintenance. ( Or even to replace the sodding bulbs when they go).
And then there is the matter of the kids' laptops. 30 machines, with 30 network connections and 30 charge points shared by 120 kids and 4 teachers with 6-8 TAs is just a recipe for device failures.
