Voice to Text Messages

Everyone uses text messages now, and they are the big fad.  One of the nice thing about them is that you can send a message to a person so they can read it later.  The biggest downfall is that sometimes its slow to type them out especially on a cellphone keypad, as our phones get smaller and smaller (and it seems my hands get bigger and bigger!).  Voice-to-text is not a new concept, but it would be a new concept with a cell phone.  One could simply speak they message, it would convert it to text for them to view, then send!
