Dave. Before this discussion becomes too arcane, may I just point out the fact that about a billion people in the world rely on SMS as the most reliable messaging technology available.

SMS is the data on-ramp for the much of the world.

So are a billion people being really stupid?

Not really. If you go to Paraguay, Thailand, Uganda or all points in between, SMS is the only universal data exchange that is widely trusted. It's about reliability. It's an expensive proposition to "go online" (as a Californian would understand it) in such countries, and this offers little guarantee that the message will get through. Hotmail, or Yahoo Mail messages sent from a cybercafe don't offer the same level of assurance as an SMS text message. Once sent, that message must navigate the oceans of spam on the open internet, and spam filters ISPs set up to thwart spam.

So it's no surprise that texting, being so personal, is so popular.

When we read:

 Most people don't realize how limited cell phone capacity really is

The translation is: Americans Need to Travel More.

Dave,

Lauren is correct. We talked about this very phenomenon in our paper "Exploiting Open Functionality in SMS-Capable Cellular Networks" in October. If you are looking for a technical perspective, please see http://www.smsanalysis.org
