In reply to gimmergimmer:
I have a hybrid with 100mm travel suspension and I have only locked it out twice in a couple of thousand miles. I certainly have not found the need to lockout for riding in the saddle at moderate speeds.
My bike is a heavy bike generally due to spec (incl panniers/mudguards, etc) and with it’s geometry, the suspension is not really that responsive, and some of the roads I use are badly in need of repair so some suspension helps for a more comfortable ride.
Personally I don’t see the lockout important for this type of bike. I actually chose suspension as I like to head off tarmac a lot to explore areas and it works as a go anywhere easy off road.
