Again, kids don't want these because they can do their school work on them.
I don't know, I had to go to school with a bunch of kids that got everything they wanted. I have to say it was pretty shitty growing up and not being able to have ever little luxury (especially ridiculous luxuries today like an iPad/iPhone) but it's funny now seeing how most of those kids turned out; lots of hard realizations that you can't get everything you want if you whine and cry long enough. I'm not even saying I had anywhere near a bad childhood in terms of what I'm got, but I respect that my parents had restraint.
Of course. Even back in the C64 and Speccy days, people extolled the educational potential of the systems while kids really just wanted to play the games. Difference between then and now is that the edutainment apps on iPad are actually entertaining and teach kids at same time. But kids will still want it more so they can play Angry Birds without having to hand it back to mum and dad when they want their tablet back.
(Also I imagine some kids get their parents older apple tech when mum or dad upgrades. Kind of like how some parents pass down their old consoles too)
In most cases these sort of things are one off gifts generally, not every kid gets a high tech gift every Christmas/Birthday. My parents made it well known if I asked for something big like that, it would be the only thing I get for that season (and maybe birthday. Usually the preceding event would be limited to a game or bunch of random stuff) . I was incredibly lucky - got a Mega Drive, Game Boy Pocket, Saturn, N64, Dreamcast, Gamecube, GBA over my childhood and I (mostly) understood when mum told me from DS onwards I had to buy the systems myself then on. I toiled weeks of babysitting for my DS and it was worth every penny! I recall lots of negotiations for the Dreamcast and Gamecube too, usually involving trading in an older system XD.
People who simply throw such gifts at their kids without stressing the value of them are the ones that suck, if you brought little tommy a DS and kept replacing it despite the fact he was more than happy to chuck it about then yeah, that kid will have a rude awakening later on. But not every lucky kid turns out to be useless with money after with the right respects to their property and appreciation for what mum and dad do get them.
