Courtesy of Reihan Salam's review of the iPhone over at slate:
"The iPhone: the mobile device that forces you to get a landline."
Apple chose to exclusively offer their phone through Cingular. One of the things people don't realize is that Cingular is essentially paying mightily to be the sole purveyor of the iPhone. It's somethnig like $100 per enrolled plan; that's in addition to the $500-$600 Apple is getting for the phone itself. But the fact is, Cingular sucks. Just seems sort of odd.
