This brought to my mind a totally absurdly cool image, in a steam-punk kinda way.

Imagine a KSR-33 teletype, on a hand-truck. Instead of the usual pedestal (or inside it) is a BIG ass battery and an inverter (were there DC-powered ttys?). There's a 20ma current loop to RS-232 adapter between the tty and the 802.11b connector...

Imagine wheeling that thing into a meeting, and then surreptitiously reading email when things get dull?

OK, that's my major retro-geek episode for the day out of the way.
