Each of these websites are really useful in telling me about the different reasons why people use iPads and for how long for, as well as other relevant information.
First, is a small article, with statistics, about the iPad, called:

Where do they use it?
Its versatility makes it a flexible and ubiquitous device with
69% of respondents using it in the bedroom

Each of these website are extremely helpful because this allows me to make a decision about the target audience I will be aiming at, and due to the information here, I am going to make my target audience Adults between the ages of 21-54, which is a huge age range, but if I can find a story that will allow for anyone in that age range to enjoy, then I feel that I could break into a market that has not really formed yet.
