they're definitely hoping the people who can't afford it simply lease it like an expensive car.

Lots of people can afford it. If you keep the phone two years, that works out to less than $3 / day. The lease option is even less. They're going to sell or lease a lot of these.

I think it's going to be very interesting to see how well the sales for the Duo do in year two and three. I suspect sales will go up, but wouldn't be shocked if they drop.
