You Should Get An Ipod Touch It is way better
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.
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.
I recommend the Nintendo Ds because it has better games. It just has a better game library than the Sony Psp & I think you'll have more fun with it. But if you only want something for media then get a Psp or just get an ipod touch.
erm no
You need to buy them off the internet on the iPod Touch.
Nintendo Ds is focused solely on gaming (minus pictochat), whereas if you get an ipod touch, you get lowered detailed games, but you also can have videos, music, and applications, my advice is if their/your younger get a ds, and if your older (teens) get them/you an ipod touch
it is only on ipod touch.
This is a matter of opinion and mainly what you wish to use it for. Music and other forms of media are certainly superior on the Ipod. But that is simply because no model of the DS is really made for such. Games however the DS has a much larger library of professionally made games and has many popular titles. If you want a multimedia device with some decent games go with the Ipod touch if the games are your main reason for purchase than go with the DSi.
ds
no seing as the ps vita has two touch screens and the ds has one but if you mean 3ds it may be better but not likly.
