Iphone 4 or Iphone 5 or Ipad?

Help?

IPad

IPhone 5. Ipads are big, inconvenient, and overrated. Seriously. An iPhone is essentially the same as an iPad, but better. It's a phone, and it can do all the same things an iPad can do, and more.

For what purpose?

To call people and use daily?
iPhone 4 or 5

To save money?
iPhone 4

To have the most colour accurate display of current selection of smartphones?
iPhone 5 or iPad.
(This was my number one consideration as I'm a photographer who appreciated colour accuracy)

For viewing documents, and general use when sitting down?
iPad

A substitute laptop while traveling when weight is a consideration?
iPad

Apple has a wide range of products for a wide range of purposes. Sit down with a cup of tea, spend a few minutes how you plan on using the product and what you need it for. The one you want and or need will reveal itself to you.

For me…
I needed a new phone, and colour accuracy was a big thing, so I got an iPhone.
Then I needed a larger display to do stuff in place of a laptop ie.showing people images, for traveling, and a second monitor to manage my digital workflow (at home and on the go) so I got an iPad. --> in hindsight, the iPad is useful but not necessary. I don't have to manage my photos while commuting on the iPad. I don't need an extra monitor to do my work. Although I will admit it make it easier. On the other hand, I wouldn't be able to function without a phone. If I had to choose, it would be the iPhone 5
