I went to the apple store with a friend last week. He badly wanted the iPad but could not find a valid reason for it, other than goofing around on the sofa. After half an hour thinking we ended up deciding that the iPad is really useful if you want a way to carry around and read your PDF library of scientific paper. I don't think it has rivals for that. For everything else it's just a cool toy.
