The number crunching is simple. For the phone I'm interested in, it's $199 down or $27/mo for 20 months, with the option to get a new phone in a year if I want one. I'd spend that in a little over 7 months, with 13 months left after that to pay (an additional $351). Obviously not worth it.
AT&T doesn't want you to know that usually after 18 months you can be eligible to re-up for most phones (including iPhones), but if you squawk enough or have a legitimate issue, they can usually re-up you after a year.
