I disagree. I think it’ll take us perhaps one more year to realize that they absolutely NAILED IT with the iPhone. The weight, the size and the ergonomics of the iPad are going to eventually prove themselves as sub-optimal in terms of everyday use. Better value than a Kindle or Nook? Of course. But that’s not saying much.
The iPhone is the form factor that will “rule the world,” specifically because of its portability. If Apple turned the iPhone into a “head unit” that could be plugged into larger screens and input devices, then I would think they are realizing the dream. But this tablet form factor is a concept that has always bugged me as “that’d be fun, but nowhere near ideal.”
