Whatcha gonna *run* on 'em? This is a design for a business, and being
able to tap into existing infrastructure (in this case, software) helps
a lot with early rounds.

See the next two.

You would, but I'm not aiming for early adoptors. I'm aiming for the
mass market, which means aesthetics become part of the functionality:
they look wierd or are at all uncomfortable, and they're as good as
busted right off the manufacturing line. You can hide a lot in a vest,
and make it look slick in many social environments.

Not on silicon, nor on most tiny chips. But when you've got area on

Yeah, but speed will be a problem and must be dealt with nonetheless.
