it all depends...
- if you are a gamer, and like to have fun, get a nintendo ds.
- if you have a lot of people to talk to that have cell phones, get the sony ericsson.
- and if you like music, get the iphone
YOU CAN ALWAYS:
save up the money, and get
Nintendo ds, and iphone.
or nintendo ds and sony ericsson
or iphone and ericsson (probally not because the sony ericsson has a built in mp3 player i think.)
