I just can't get passed the implicit assumption that this guy doesn't live in the real world. There have been prepay cellphones as low as twenty dollars in the U.S. alone for quite some time. And yes, they can text and have removable batteries. I own one of them.
That's true, I've had one myself :) But still, in some countries, the difference between 10 and 20 dollars could actually be significant. It's easy to forget that with so many smart phones in the US.
Yes, I didn't mean to say twenty dollars was an insignificant amount for most people. A ten dollar difference does matter. A penny matters if the storekeeper wants the full price and you lack a penny.
