iMessage ate my text messages

I have been on an unlimited texting plan for as long as I can remember.  Recently I thought I'd check out how much of texting do I actually use.  It turns out that with introduction of iMessage and Facebook messaging client my usage of text has been less and less.  AT&T is paying attention to that a lot more than I do and of course they have killed the ability for folks to downgrade their plans.

There is no way to say: "I don't accept text messages" so draw your own conclusions.
