Stumbled across this, which is an episode of Computer Chronicles on PDAs from 1993. The preview alone is good, although the AT&T combo cellular phone/PDA is funny. And people today complain their PDA phones cost $400 - that one was $2100. In the "Random Access" portion they talk about the announcement of the win32 API to allow things to work across different versions of Windows. I had all but forgotten about GNN too.

I chose to believe that PDA still stands for "a great way to gross people out when you and your boyfriend are out on the town."
Yes, yes, I know what a PDA is...
