Will iMessage Kill SMS?

"Apple just barely announces the existence of iMessage and the world screeches to a halt. Blackberry stocks take a dive and the future of SMS in the US is called into question. And I'm personally left feeling very confused."

The confusion comes about due to the reaction of the markets, with talk of Apple's iMessage function bringing about the death of SMS as we know it (this article for one). I certainly don't believe that, because, like Apple fans, there are Android fans, Blackberry fans and fans even of the old faithful flip phone. To think that iMessage is going to significantly alter the course of messaging is rather ridiculous. Granted, it will be a nice option to have but only between iOS devices, and I will still have a need for SMS on my trusty iPhone to communicate with friends that have chosen to stick with the Android platform. There is no all-in-one app out there that has captured EVERYONE's interest so until that happens, I think SMS is safe. If you are interested in a good run down of the iMessage function, Apple Insider has a pretty good article here. What are your thoughts?
