Hi Torque,
I certainly wasn't suggesting that crew comonality was a bad idea! I'm not certain it is as big a selling point as Airbus (or, for that matter Boeing with 757/767) would like it to be, but obviously it is an advantage. I've just felt that while Boeing can use a clean sheet and be as inovative as they like (if the end result can be made backward-compatible all the better), Airbus are constrained to make rather convential aircraft in order that they can be made to look (display wise) and fly like their previous products.
I feel they have made a huge commitment to an aircraft that will cost a LOT to develop, and does anyone think they'll ever sell 2000 of them, or even 1000?
