ham, When disc brakes appeared in the automotive and motorcycling worlds, the advantages were pretty apparent. In bicycling the advantages are less apparent, but are there in favor of discs, primarily braking performance when wet. Marketing strategy will assure more bikes are disc braked.

That written, I have nothing against disc brakes yet have no desire to equip, nor replace, my rim braked bicycles. If disks give you some extra assurance, the added expense is worth it.
