I have my mother in law and my brother in law, they both have droids with speech to text. They can compose mms, email's perform searches etc. Pretty convenient for situations were you can't type (like in the car). I have done some searches on the app store, but have only found text to speech or specific apps, nothing that is integrated across all of the apps that could use it. Is there something I am missing? Is there one out there? Or is that what you think Apple acquired Siri for?
