What we need is someone to teach us the basics about how it is useful and how it is compatible with our existing operating systems. We don't get a choice, ya know. Whatever the school buys, that's what we get.
I'm planning on giving a talk at a future math conference on applications that are helpful (GIMP 2.0 for making graphs, etc.) You have to understand, too, that many teachers are aged, and can barely start up their own machine. Focus on the young teachers and you'll have your solution.
