John, (and group)
IM(very)HO, I've always felt a more distributed modular "brick" would be
the way to go, AND still follow the original design of the concept of
the core brick.
these guys are my inspiration:
http://www2.parc.com/spl/projects/modrobots/chain/polybot/g3.html
for a future RCX, some sort of standard "block" with on board smarts,
and enough power to run 2 motors, and 2 sensors.....
want more motors, (or memory, or I/O port) snap on more blocks.
but this has been suggested and debated before.
