Things being normal does not mean they are a good idea. How will teaching a class of 30 be improved with the addition of 30 tablets or smartphones, apart from in the rare occasions that you are teaching how to program the things?
It’s funny how you seem to imply that the only useful thing you can do with a computer is to learn how to program things.
It’s not going to be a revolution or a huge improvement (better teachers are the most important thing above all else), but being able to use modern tools seems kinda important to me.
(Do you have any idea how much Grapher† helped me understand math when doing my homework? I wasn’t programming, I was using a modern UI – no stupid graphing calculator that’s a pain to use – to fool around with equations. That was tremendously helpful. Having that kind of power always with you, instant on, with a battery that lasts forever, man, that’s living the dream.)

And given the distractions that a group of schoolkids can create using just pen and paper, I don't see how devices that are primarily designed for consuming media and gaming are really going to help much. Half of them will get broken or stolen and the other half will be hacked.
