Since you asked HC.
If you had a Decca Roll map (or even an RNAV2) and an all-singing and dancing FMS with GPS what would you choose. I'm sure both systems would get you from A to B but I'm equally sure you wouldn't choose the old system.
I don't have enough brain cells left to remember all the call-outs from both systems but what I do know is that the EGPWS is a step in the right direction. At the end of a long day you do end up coming back onshore and having the extra situational awareness that the EGPWS brings has got to be good.
BTW, unless it's changed, the voice on the EGPWS comes from a chap called Noel. If you think that's bad, you should hear the voice that emanates from the system in our S76.
