Wow dude. *Whoosh* Do you hear that sound? That is the sound of the whole point of simplicity going right over your head. The iPhone is meant to be a smart phone for "the rest of us". The UI is designed to work well as not only a smart phone for consumers but also to work well as an iPod. Did you notice that the iPod touch and iPhone share the same basic UI outside of phone and SMS functionality?
If I wanted a complicated business phone that is mainly focused on email, then I'd get a Blackberry. If I was obsessed with features, I might get a Nokia. But since I actually work in the technology sector, I don't give a rats arse about geeky crap like that when I'm not at work. I like to keep things simple while off duty.
One final note. I think that intelliscreen is stupid. Why would I want what amounts to an outlook today broadcasting to everyone who sees my lockscreen what email I have waiting? Isn't the whole point of the locks screen to keep things private? It also is a horrible waste of battery with all of those background processes running and I've heard of people having to restore their iPhone after two jailbreak hacks conflicted with each other.
I guess I too am overlooking the intention of the iphone which probably means I am not part of "the res of us" crowd.
