You mean compaired to other comm devices, or compaired to a couple motors?  I'd
think if you have a moble robot, the motors are going to use much more power 
than
anything else, right?

And, to me, that's a problem.  This is the first time I've heard of Zigbee.  I 
know
I can go out and get a BT card for my laptop.  Or, I can connect with my PDA.  
Is
that same hardware available for ZB?  Where will ZB be in a year?  In five 
years?

It seems to me that LEGO is NOT a technology company.  They don't design or 
develop
new technology.  They make toys.  Toys that use existing technology.

Seven or eight years after the RCX came out, is it still cutting edge 
technology? 
No.  In fact, I don't think it ever was.  But, it's still very cool.

I think LEGO has to leave it to people like you, Gabe, and John Barnes, to 
create
cutting edge stuff.  They need to stick to solid, proven technology.
