How many children do you have? 4? 5? 6?
😱Anyways, I don't suggest you get 3

iPod touches. It's way too expensive. And if you can afford 3 of them, why don't you buy the new one?
😕
Consider what your children want the

iPods for. If they want it just for the touchscreen, I would advise you to get a cheaper touchscreen mp3 player for like $100-175 (don't get generic brands
😡). After all, one of the main reasons I bought a touch is not for the controls, but for the WiFi!

Also, consider how old your children are. If they are like 5 or 7, don't get it. It's too complicated for them. Maybe a simple mp3 player, like a shuffle, would be fine. On the other hand, if they are like 18 or something, they should buy their own.

Finally, do you REALLY NEED three

iPod touches, in which could easily be broken or "stolen".

Sorry for all the smilies.
