Plans for the Apple III were a little bit optimistic:
"Voice and character recognition are both being considered as built in features. Possibility of UHF very short range transmitter for wireless display capability depending on FCC approval."
It's interesting to consider how different technologies alter the evolution of each other: e.g., if hypothetically display technology had stalled and we were limited to 512x342 black and white pixel screens, I can easily imagine that wireless displays would be the norm. So it sounds crazy reading that now, because we have these huge colourful displays, but back then maybe it was reasonable. It's just that history turned out differently and display technologies progressed far faster than wireless transmission standards (and the processors necessary to drive them).
At least in Europe, the Amiga had this... the RF output was strong enough that you could use it as an antenna and get it from the other side of the room, complete with snow effects :)
