Where does it state thet the board will be shown in working/final stage ?
They dont, and im fully on you with this one. I assume their showing a board that wont run anything. Ie, it wont even be pluged in. I assume some people like to see these things for the real thing because their electronic freaks and like to see the logic up close

I'd think it would be too soon for these boards to run anything. Again, i assume!
