It's not really necessary for anyone, but it is quite a nice luxury. I was at the beach last week and a friend (a highschool English teacher) recommended a novel that she teaches her students ("The Sparrow" by Mary Doria Russell; it's great so far). I was so intrigued by her explanation of it that I bought it then and there, sitting on the beach, and started reading it 30 seconds later. So I expect that those who can afford it will. That said, I keep the 3G off when I'm not using it, because it tears through the battery, even when the Kindle's off(!) so that it can always receive new subscriptions.
