Well, it's more spirited discussion than fight. The concerns you give voice to are widespread which probably is why I reacted so strongly...now if you'd criticized the weight of the Edge it would have been even worse!
I would guess the difference in price for the different colors is probably due to Entourage ordering a ton of Midnight Blue shells, and getting charged less per unit because of the size of the order, while they have to pay more for the other colors because they order fewer of them. If they'd ordered equal numbers of each color and then it turned out no one wanted to buy the light blue ones, they'd be stuck with a lot of devices they couldn't sell because they were the wrong color.
Personally I don't get the appeal of the light blue or red ones. Midnight blue and black are professional-looking colors, while the white might appeal to people in love with Apple's aesthetics (ugh!).
