I've read the information about push mail, push contacts, etc. but don't really understand how this works for the Ipod Touch. I still won't get my e-mail if I'm not in a wifi hotspot, right? What does it mean when it says it pushes it over the air? What's the big deal about having to hook your ipod up to the computer....that's not an inconvenience. When I delete an e-mail on my ipod touch now, it deletes it on my computer e-mail without having to sync.
