Google Voice
I just upgraded from Grand Central to Google Voice. I have been waiting for this transcription feature forever- I'd been using PhoneTag, but it wasn't quite the same. I don't want anyone to call my cell directly again! I have a feeling this is going to be an extremely popular service- it really puts the receiver back in charge of voicemail. Often I'd feel my time was being hijacked by people leaving inefficient messages. Text wins.
