Got mine on day one, myself. Having used just a regular old flip-up cellphone for the past for the better part of two decades — camera-less, no less — the iPhone4 has overwhelmed me. It definitely fills in my downtime at work.
And it’s true: It’s more a computer than a cell phone, but it’s definitely both, and what’s wrong with that?
So far, I’m enjoying it. However, perhaps someone could recommend a book that I could read to teach me how to use the damned thing. I’m sure after a few days, I’ve merely scratched the surface. (Not literally, since I purchased the requisite cases and protective screens for the phone.)

And that is the reason why "cell phones" are dead, as are "phone networks". Both the iPhone and Android devices are essentially mobile computers that have the capability to talk to a particular legacy network (the voice telephone system). This has been true since the iPhone 3G's introduction of the app Store in 2008.
The iPhone 4 represents something of an inflection point. It's a great piece of technology combined with masterful design and marketing. Apple has both pioneered and become the master of the technology fashion market, which is why it's product launches have become such media circuses.
