All interesting points, I fly the 727 and there are a few things about the cockpit that I'd have designed differently, But you have to realize the cockpit on the 737 is essentially the same cockpit designed in 1952 for the dash-80 (the prototype 707) I agree Boeing should have an auto-stow feature for the speedbrakes, The C-141 has it and it was designed in the early 60's. But lets look at this from a marketing standpoint, If Boeing totally redesigned the 737 what would all the existing 73 operators do? buy the new 787? obviously alot of airlines are happy with the 73 as it is so to totally redesign it may have been a huge and costly risk. One final note, and all you Airbus fans please dont whine! Airbus is selling their A-320 at an extremely low price vis a vis the 737, so a new design would invariably cost more than the existing 737 and would make it non-competitive with the subsidized Bus!!
