It stands to reason that people aren't going to use the technology if it's unreliable (or reliable only in the sense that it is certain to go wrong), or that getting a problem sorted out takes ages.
Therefore today, I have just one question for you: what is your technical support like?
In my opinion, the best technical support is that which is completely invisible. Things tend not to break down because only the best was purchased in the first place, and because the technical support folk are proactively monitoring and maintaining all the systems in use. When, in the unlikely event a piece of equipment does go on strike, it's replaced within hours, or even faster.
Is that a counsel of perfection? Is it pie in the sky? I don't think so; in fact, I know it's not the case because I've seen ordinary, urban, working class area schools achieve exactly that. Yes, even primary schools.
So again, I challenge you: what's your technical support like? What would you like it to be like? What needs to happen in order to bridge that gap?
