Why not? All it would take is for Apple to standardize the spec and all of a sudden your BlackBerry/Android using friends are on board. My SMS usage is going to plummet with just iPhones on board, but add in the others and I'm down to reminders that are sent programmatically.
I agree with jbondeson and in addition to that, Apple probably won't want to standardize and share this, it's a new incentive they've created to buy an iOS device.
Because it would be better for every handset maker to not be held by the nuts by carriers. In most markets Android has more market share, Apple would be wise to be able and set the standard for future messaging.
The iPhone has 4-5% market share of worldwide mobile phones. Even if you could get every smart phone manufacturer to convert that still would only get you to a ~20% market share.
The fact that the iPhone has a 5% market share does not mean it represents 5% of all SMS messages sent. Smartphone users text message more frequently than your grandmother with an LG handset.
I would argue that the frequency of SMS usage has very little to do with the type of phone you have, and much more to do with the demographic. There are plenty of iPhone users (such as my mother) who don't use SMS at all, and plenty of 14 year olds without smart phones (like my cousin) who text dozens of times a day.
Either way, I've never seen a breakdown of SMS usage by either category.
I had peers in junior high/high school (before I even had a cell phone) who sent hundreds a day. One girl bragged about reaching something like 30,000 one month.
It doesn't have to go anywhere soon in order to die a slow, painful death. Moreover, it's a question of one's social circles. In my case, it hardly matters what the worldwide share looks like since nearly everyone I currently text has an iPhone.
