And in my case, there are no IT employees at all. For some reason there is budget available to buy the hardware and none to maintain it. This is changing slowly but for the moment it's the unfortunate reality. So it's up to teachers and volunteers to try and make things work, and as you were saying if things are too difficult they just stop using them.

And a side note, I was a Windows user for a decade and have now been a Mac user for a decade and the level of maintenance required for a Mac is _easily_ an order of magnitude less than Windows.
