To be fair, I think WeDo is targeted at much younger audience than the RCX
and NXT. The chart on page 2 of the Dacta catalog actually specifies it
as elementary school only, while the NXT is elemetary school through
college. Which means WeDo might be around my level of robotics
expertise. . .

I saw that in the catalog. I wonder if that's so people don't daisy-chain
them (which I believe the regular Power Functions do) and interfere with
the sensing or software? If so, what happens if you use a Power Functions
wire to get around that?
