What I'm seeing is more and more web based systems. My kids school is completely browser based. Nothing is installed beyond the browser. Same for the teachers, it's all web based.
That said, I love apple. Nothing else works like their hardware. It's not the best by a long shot, but I'm still able to use a mac-pro 8 years on. And my iphone is 7 years old (for me) and I got it used.
you should start teaching him before he thinks ^above^ is normal, rather than most conveinient for the school, let him know he will have superpowers.
