I do hate to be cynical, but I get the impression Boeing are releasing this more because they felt it was time they released a new plane, than because they actually had any worthwhile purpose. Not surprising then that it looks like all the other Boeings! It's like when The Stones decide to release another Best of Album! Maybe they should call this the "Best of" airplane!
As for the kids with the laptops - maybe they are trying to cut costs with employing designers? who knows?
