WWW, I'm equally biased and glad the 800 and 900 have the same start control panel as the 300 and 400's.
It may because I'm getting older but I'm getting less and less impressed with gadgetitus. It's a disease that many of my colleagues have. They think they can measure their libido by the look and size of the toys that the boss allows them to play with.
The only real and serious improvement that may really make life better and, hopefully, a bit longer for a few of us is the EGPWS with the terrair feature. The lower flightdeck noise level is an other advantage. The rest is, from this pilot's point of view, mainly cosmetics.
As an old -200 captain once told me about the -300: "It's just the same old lady with a facelift"
I presume the -700 to -900 have had a silicon refill on top of that.
I still like Mrs Sq as she is.
