One day I was getting a haircut in my smallish Midwest hometown. Another customer was grousing about being unable to contact a friend, and just happened to mention someone I knew. I pulled out my Palm and said I had their phone number. The guy also pulled out the Palm that he was carrying, and I used the IR sender thing to share our mutual friend’s contact info. My barber was like “what in the Star Trek just happened”?
I didn’t know the other guy. We had a mutual friend. We both had Palms. It was a whole list of unlikely coincidences that had to line up well. It surely did feel sci-fi. That was the one and only time I ever used that feature.
