Sounds really good Thad.

Yes, I like this! I've done a lot of road er sidewalk time and tried 
to see if I can really make the wearable useful on the sidewalk, in 
my car, and in restaurants and coffee shops etc. I once went for one 
full month tracking my every move logging GPS coords to a server on 
the net (which meant 24/7 operation). Small things like comfort and 
ease of use become very important. That's why I put a display on my 
wrist (sleeve) and buttons on my cuff, two seconds to switch on 
applicances or launch x-windows or display my shedule, grab camera 
images, etc. I agree with Brad, if you have to pull something out and 
attach this and that, or do a long sequence of commands, it loses the 
whole point of wearable assistance. And if its too involved Brad is 
right, you won't bother. My vision is one of total integration, with 
relays and switching circuits managing connections between various 
audio and video components, voice and data networks, any service on 
the wearable. Some day I will get there ...

Thad: I have a suggestion for Charmed. Sell us power kits with the
charging circuitry. Everyone wants this and nobody has it. Its time 
to move beyond the battery swapping routine, that in itself goes 
against Brad's principle. If Charmed made a power kit with AC/DC 
adapter, small charger/monitor board w/rs232 interface, and battery 
packs, I guarantee you that many people here would buy.
