Correct me if I'm wrong, but the subscription to MobileMe is Apple revenue, not AT&T revenue, right?
So, if you're trying to figure out where the subsidy gets recouped, it makes no sense to add in the cost of MobileMe! Heck, if the guy is going to compare feature-to-feature, then he needs to jump into the muck of the AT&T plan, since the additional $5/mo for SMS smells a lot more like subsidy-recoup than MobileMe does!
And, of course, he's saying that you have to go into an AT&T store to buy the iPhone??? Where's he getting that -- you have to activate at point-of-sale, but that point-of-sale can also be an Apple store!
And then, he's also claiming that one might upgrade to iPhone 3G in order to get the App Store and email sync... umm -- that's software (iPhone 2.0), not hardware (iPhone 3G)!
sigh...
