What apple devises should some one need?

I'm looking at having a iMac, Macbook, ipod, and iphone. But i don't have to have it all.
I'm student at a boarding school how likes to blog, take a lot of photos and I do make videos sometimes. As well I would like to do most of my work in my room but as well I need something to do my work out side my room when i meet with the other younger students. As well I spend most of my time studding. I want to have an Ipod that just plays music so that it helps me be less descanted. But as well I like to type my notes most of the time.
but in all if you don't see the pint in me having all that stuff that is okay.
It is okay if you need to ask my a question so that you can decide what I need.

You really only need a MacBook and an iPhone.

- You can do work outside your house on the MacBook
- You can do work inside your house on the MacBook. If you need a bigger screen, just buy a monitor and attach it.
- There's no reason to get an iPod if you have an iPhone as iPhones are iPods with cellular connectivity.

For working out nothing beats an ipod shuffle, its so tiny and clips on anywhere and I don't want to be carrying a phone while doing that.
