If there's anything that's important to teach your kids, it's the value of saving money and being fiscally responsible. If there's a way to do the exact opposite of that, it's giving them a touchscreen ATM. It makes taking money out a game! When you've got all your money out, you can just put it back in. There are no consequences!
I guess if the kids used this as a serious bank for saving money and they didn't treat it as a toy it wouldn't be so bad. But come on, it looks like a toy! Let's teach kids that ATMs aren't endless money machines, and instead are to be used responsibly, otherwise they'll blow their college savings on pixie sticks and Ninja Turtles, or whatever it is the kids like these days.
Holy crap, when did I turn into a crotchety old man?
