This should be tattooed on every single iOS dev.
PS: I actually wish there would be at least few 30-60$ games in the store. And not those crappy ports of gamepad/mouse games (shooters etc.) with unplayable controls. Or some good, but very old, not so polished ports of ports of classic games (FFT). It would be nice to play some great western RPG, with interesting story (not that boring save the world stuff), it should be turn based to adjust to device controls, some good graphics (not like those Top games from store) - look up Bastion on the PC, THIS is how AAA iPad games should look like. And no sequels. Please.
I don't know the answers, but I think it's reasonable to ask whether technology can make a positive contribution to kids' lives. I don't think it's productive to belittle people for experimenting with ways of doing so.
