IPad

I have a question to those of you who own iPads. What are the benefits? We had one at work over the holidays to do some testing on and I honestly don't see the point of them. It doesn't seem to do anything that my iPhone can't do, and my phone had the added bonus of being able to call and text people. Aside from the testing the only thing I used it for was watching some TV on iPlayer, which I could have done on my laptop just as easily.

I'm just confused about why iPads are still so expensive when they don't seem to really do that much.
