My boys love their kindle fires, but I have no experience with the other so I can not say for sure which is better. But I am also not sure I would let the kids pool their money on something so big at such a young age, I would try to save and then eventually give them each half of what they need so they can each have their own. If that means not having it for this trip then so be it. And frankly, if the other kids have tablets they are not allowed to share then I would set the rule that the tablets then need to be left at the mothers house. That their mother would take aim at your kids like that is just thoughtless and cruel. There is nothing wrong with saying that if they are not allowed to share that the tablets are not allowed to come to your home.
