The iPad is worth it to me. The reason a lot of people are skeptical is because most people have a smartphone and a laptop. Therefore, it's harder to justify the iPad purchase, even though it still can be a great addition.
It is worth it for me because I don't have a laptop and only would use it for music, school work, web browsing, email etc etc. My desktop is going to handle all tasks including photo editing, music downloading and so on.
The iPad is cheaper than a laptop, lighter than a laptop and does all of the things that I would use a laptop for. And it's touch screen.
