(Sorry for the mislaunch earlier, this Netscape Messenger is driving
me up the wall. Due to unfortunate intereference between a MTA
misconfiguration and the local potsmaster I have to temporarily
resort to this festering piece of brokenness.)

Why? Plastic transistors have their niches, but wearable CPUs are
not it. Displays, possible.

If you're talking wearable hardware, I'll be very happy with a fannypack
and a decent headset/headup. Sewing stuff into cloth is silly.

Chip real estate is not cheap, not in the world I woke up in today.

If your transistors are made from plastic, relativistic latency
will be the least of your problems.
