Also, a lawyer friend at a top tier law firm was offered the iPhone as an alternative as well - granted he didn't take it. A decision he regrets.
It's only a matter of time - no one wants to carry 2 devices and their employers are keen to it.
I can type faster now on my iPhone than I ever imagined possible on a mobile device, thanks to three things: autocorrect, adaptive key hitboxes (look up the patent; it's pretty cool), and the lack of tactile feedback.
Yes, lack of tactile feedback. Merely making contact with a surface takes slightly less time than pressing the travel distance of a key, and it adds up. In my experience, the loss in accuracy from lack of tactility is more than compensated for by the iPhone keyboard's advantages.
My friend just dump iPhone for BB because well... his friends are using BBM.
My father works in Bank and him and his friends and all of his business partners don't bother to look at iPhone/iPod/iPad.
