Sorry, accidentally sent this before I had written it:

Small battery-powered USB charger:
http://www.ladyada.net/make/mintyboost/
I assume above should be able to charge Neo1973?

Battery-Powered 4-Port USB Hub:
http://www.amazon.com/Cyber-Power-Battery-Powered-CP-H420MP/dp/B0002UQALQ
I suspect above can't be used to charge, only for connecting USB devices
to Neo1973. If it can be used to charge, then probably can't act at same
time as a hub for Neo1973 at same time (loop).



Ideal would be device that combined best of 2 above into one device:
1) 2 AA batteries: better volume/energy ratio than AAA and better
price/energy ratio too. With enough rechargeable batteries you have
almost unlimited runtime.

2) Charge Neo1973.

3) Power and ports for up to 2 or 4 USB gadgets. With this you can use
WiFi, get images from about any digital camera and with some models
phone can snap images directly too. Gives access to at least 160 GiB
battery powered USB drives too. This makes Neo1973 computer that works
with many USB gadgets.

4) As small as possible given above


I wonder if it could be made to work as a sleeve? Even then you should
be able to use it in tethered mode by adding suitable cable between
sleeve-hub and Neo1973. 

Instead of sleeve it could be different back like described at wiki:
