It’s like the iPad was a device we never knew that we needed. Until Apple gave it to us.
That is the job of effective advertising, to make us need products that we didn't need before. Apple is good at this. I know I don't really need an iPad, and am determined to wait until the second generation comes out, yet I can't help but marvel at the effectiveness of Apple advertising and media coverage which makes it seem like the iPad is something everyone "needs".
