you probably could.. but it wouldn't be free.
no
i don't think so
It depends on what your style is. If you already have a DS or DS Lite but no iPod, go for the iPod Touch. If you already have an iPod but no DS or DS Lite, then go for the DSi.
pizzazz touch lite
You can't save in the lite version of the game
Some are and some are not. It depends on which one and if it is lite.
Yes I have had twins and you can have triplets
No, you can have lite and full version, but not 2 of the same
If you already have a DS Lite, then there's virtually no point in getting a DSi. You should get an iPod Touch, since it already fulfills the DSi's main features (that aren't playing DS games) and more.
The lite version has a limited number of daily texts.
If for iPod touch on only 1 child sorry
some games you have to pay for but some are lite versions or demos.
