The True Cost of SMS Messages » a gthing science project
Here’s a great analysis of the comparative cost of text messaging, including something I’ve wanted to do for awhile, a price comparison of how much you can fit in an SMS message to a regular postal envelope. The author comes up with a rate of 14kB/$.41 for letters, and 140 bytes/$.20. I think that’s something like 48 times more expensive (per byte/penny).
I guess this answers the question of why we Americans don’t text as much as other places in the world.
