Nobody was making products that resembled the iPhone before AppleYears before the iPhone I was carrying around an iPaq. Now it isn't quite the same, most notably because the original device didn't even function as a phone. Yet I would argue that the phone part of smartphone is by far the least important part (and the only reason it is so prevalent is that carrier subsidization allows people to stomach $700 iPhones). Really these things are ultra-portable computers and the phone thing is ancillary.
The iPaq wasn't multitouch. But here's the thing -- Apple bought that multitouch sensor. They didn't invent it. They didn't specify it. They didn't even initiate its creation. Their software used it brilliantly, but by the common narrative you'd think they had invented it.
Capacitive touchscreens evolved. Embedded processors evolved. GPUs evolved. Wireless technologies evolved. Batteries evolved. Makers like RIM pushed much of that evolution.
Apple stepped in at the perfect confluence of technologies and made the iPaq v2.0. Better in every way -- largely owing to those hardware improvements, all of which came from outside Apple -- but did it really invent an industry?
It's actually a bit sad how little credit RIM gets, given that they were the ones who pushed a lot of the innovation in mobile that made the iPhone possible. A distributed messaging, application platform, camera, etc...everyone just focuses on the damn keyboard as if it defines the platform.
Already I'm seeing many ascribing the iPad as inventing the tablet, forgetting so many products that came before (both real, such as Archos, and conceptual like the Crunchpad). Apple executes amazingly well, but their creations are seldom as out of left field as people imagine. They say that the victors write history, but it is sad if we're blinded into confusing commercial success with innovation.
