Re: Er, iPads?
Further to the other comment about "why iPads?", wouldn't kids in schools and in particular Special Needs kids actually be better off with something a bit more rugged? I'm pretty sure that nothing about the iPad is actually unique apart from maybe the price.
Also I'm not a huge fan of the whole locked in OS thing, in my opinion the Apple strategy is worse for the consumer than the whole MS strategy, at least when you bought a PC with a MS OS installed you could still get support for the hardware in the event you replace the OS.
