Where I am, unlimited texting is pretty much standard as part of any reasonable phone package, it's not something we pay discretely for. Couldn't get a reasonable data plan without it. So not sure if there are any savings to be had since you'll probably have to have a data plan to use it anyway.
I expect that it's not SMS that Apple's going to kill with this though. It's Blackberry's BBM service they're looking to kill.
Now would be a good time to short RIM :).
