You know what would be really cool? If you could beam a business card, appointment, whatever, to another palm over the phone. Each palm has a speaker, and visors, at least, have microphones. Someone (palm) should make software that emilates a 300 baud modem, so you can just choose 'audio-beam' and put the palm up to the phone, and the other person puts theirs up to the phone, and you can send the card, appointment, applet, whatever.

One step further, you could have an answering machine or voicemail system that says "Press 1 to leave a message. Press 2 to receive contact information to your palm. Press 3 to (buzzword, 'a-beam'?) your contact information from your palm.' (or other device, whatever).

Funny how sometimes it's hard to tell the difference between a step forward and a step backward, like closed-circuit TV --> broadcast TV --> Cable TV --> 'wireless cable' digital broadcast TV --> Broadband net access --> Two-way satellite links...
