Earlier quoted context omitted.
Is the iPhone really an amazing new discovery that came out of nowhere? I see it more as the result of inevitable cost reductions in recent technology (fast/low power CPUs, capacitive screens, better LCDs, higher density batteries/flash/RAM)...combined with a willingness to tell the phone carriers to suck it and do a phone the way Apple wanted to do it.
Ever since the first Palm PDA came out, it was obvious that the iPhone was going to happen. I was drooling for something like it back in '98 ... '99, or whenever it was that I bought my first Palm. I was like, "okay, now let's combine this with a cell phone, and add more CPU, and more memory, and a color screen, and..." Alas, it was not to be, yet. But then it did happen.
Even Jobs has wanted to make a Dynabook from the early days (http://www.folklore.org/StoryView.py?story=Pirate_Flag.txt).
There was also the crew from UIUC that won Apple's "Design the Computer of the Year 2000" back in 1987. Their design? A tablet.
