We've had this discussion before but good cup-and-cone hubs (Shimano and Campy among others) can be extremely durable with even a modest amount of care and maintenance. Two cases in point:
My 7700 Dura Ace hubs have well over 55,000 miles on them. They still have the original cones, races and freehub body and have been overhauled and relubed at perhaps 7000 - 8000 mile intervals. They are still in daily use with no signs they are going to "trash" themselves anytime soon.
I also have a set of Campy 10-speed Chorus hubs with about 30,000 miles with the same maintenance schedule and all of the OEM parts still in place. These hubs are also in daily use and appear to have a great future too.
