Which one should I get? An iPhone or an iPad?

I'm allowed to ask for one really big Christmas gift each year and I would like to know which one is better, the iPhone or the iPad? I don't know what you can do on either, not really anyways. Could someone tell me? I know I want to be able to watch TV shows on it and I would like at least a small bit of access to the internet. Music isn't a big deal for me though I wouldn't mind being able to listen to it. I like to write, which one would I be able to type up quick notes or actual word documents? I'd really appreciate the help.

If you need a phone then go with iphone, it really depends what you need

It really depends on your needs. Both the iPhone and the iPad will perform similar functions in terms of displaying videos, playing music, games, apps, etc. If you want to create documents and don't care about the phone piece, go with the iPad as the screen and keyboard will be larger and easier to type on. It will also be nicer watching shows, movies, etc. On a screen larger than an iPhone.

If you need the phone, there's only one option and that's the iPhone.
