I wonder how much more viable this camera would be if TLG looked into the 
possibility of outfitting it with something similar to BlueTooth?  While the 
data transmission rate would be low, I'd imagine they could get it to send 
some sort of picture back if they adapted a radio frequency to carrying it. 
I'm not sure that BlueTooth itself would be viable, being that they've 
already got the NXT communication with that, it'd probably be messing the 
communication channels up with picture data.

I sometimes wonder if TLG underdeveloped the camera they bought out, I 
reckon some on-the-ball development staff could make a new one considerably 
better than the original.

So should TLG - if someone says a new camera can't be done, maybe they 
should look around for a camera manufacturer looking for something to put 
their camera into and see if they can't pair up some decent camera 
technology for NXT.
