Re: STAR TREK INTO DARKNESS - Grading & Discussion [SPOILERS]
Seems like the communicators also used text messaging. Pike was called to the meeting reading something. They are more or less cell phones at this point. But then again the cell phone was inspired by the communicators from TOS.
And yet greatly superior. Rewatch The Cage and check out how the camera focuses on Pike's communicator at the beginning like it's some amazing piece of tech. Kinda funny now.
And that's my opinion.
