I like it.

Yes. Absolutely. Over one half of the current RCX is batteries, and
another quarter or so is IO ports. I can see a very small mini-RCX
being possible, especially if you make the display smaller or remove
it altogether.
What you need is a power port the same size as current external power
ports, which can accept either the lead from the current
power-transformers, or the lead from the external battery box. The
battery box itself should include a bit of trickle-charge circuitry
(can be done in very little space and cheaply nowadays) and an input
port for the external power connector, making it dual purpose as both
a battery box and a rechargeable battery charger.
What do you think?
