I'm actually losing money waiting for iPhone X, since I'm on Apple's iPhone Update program.
In the program, you get a phone and pay a monthly fee, let's say $40. After 12 months you've paid around half the retail price. You turn in your phone and get the new model. But in this case, the new model is late, let's say by one month. So I send up making a 13th payment while I wait, then get the new phone and start a new cycle of payments. Now when the phone after that comes out, it has only been 11 months. Not only had I paid 13 months on the old phone, I have to make a double payment at the 11 month mark to get the phone on day 1 - else I'm always a month behind forever.
