For the third time now, AT&T already offered that plan.
There is no difference between the iPhone Data Plan and MediaMAX.
I'm willing to bet one of us works in the industry, and one of us does not.
If a typical not-Blackberry user takes their device to their IT department and complains, they're usually going to be sent to their carrier. It is completely irrational to expect an internal support department to provide support for every device on every network, without buying them every device for every network.
And yes, Apple could very easily license Mobile ActiveSync. But the point is that they haven't yet. If (or when) they do, the iPhone will almost certainly be offered on business plans.
As a former BlackBerry user, I can certainly attest to liking the iPhone. That's why I have one. But at the same time, the e-mail, contact sync, and note sync functionalities are absolutely incomparable.
If you were comparing BES to WM+Exchange, that would be something. But the iPhone's e-mail abilities (as currently enabled) aren't in the same league.
