I've been moved around a lot my whole life, been to more than a few schools. But the only one that ever had Macs was my first elementary school, They had just bought a lot of the brand new iMacs to replace all the PowerMac 5500's they had had for a while. I pretty much learned how to use a computer on a Mac. (though we had PC's at home I had used for a while before then, I actually learned stuff in school at the time. 😛)
I remember a lot of the classrooms having various models, from more of the AIO PowerMac range, to the pizza box LCs and even a clamshell iBook or two. There was one special music classroom that had a few PowerMacs, but also had a functioning Apple IIe and IIc that had great music programs. (All the other kids hated these old school machines, but I was absolutely fascinated. 🙂)
Alas, I moved away from there in 2nd grade, and I never went to a school with Macs again.
