> What was novel about the smart phone - really it's defining characteristic, was it wasn't a primarily single purpose device like a PDA, or phone, or MP-3 player/iPod, or camera, or handheld web browser, but rather a universal hand held computer/communications device, and one whose functionality was not limited to what you got out of the box.

I used a Palm PDA back in the pre-iPhone days. Its functionality was not "limited to what you got out of the box", you could install applications on it. I have fond memories of exchanging Palm applications with my friends through its infrared port. I used it as a PDA, MP3 player, camera, to play games, and even as a handheld web browser (it didn't come with a web browser, it was one of the applications I installed), using a Bluetooth connection to my cell phone for the network access. The only thing it couldn't do, was making phone calls; for that, I used that cell phone on my other pocket. That's the defining characteristic of a smartphone: being a phone which can do all the things a PDA could already do.

> and questioned who would want it, given the high cost and lack of a keyboard (a feature, not a deficit!).

That Palm PDA also lacked a keyboard. It was designed to be used without a keyboard, and worked pretty well, with either the stylus or the on-screen keyboard (which was usable even without the stylus). So it was not a given that the lack of a keyboard would be a deficit.
