I see them fading away just like netbooks or PDAs. People are only buying the ipad because it's an Apple product, and you'll always have hipsters and morons willing to buy their crap. Just look at how badly ipad competitors like the Xoom have flopped. Even the ipad 2 didn't do that well. Its launch was a fart in the wind. I think the problem is that they don't do anything particularly well. They aren't portable like a smartphone. And they aren't powerful like a laptop or desktop. They're also majorly overpriced. Who's going to shell out $800 for one of these things when you can get an i5 or i7 based laptop for that much?
