Is it likely that brake pads will wear more quickly with the SBS system?

Quite frankly, SBS has about convinced me that the new W211 isn't for me even though it's an amazing car. I could adapt to the new system and I suppose my wife could also (with some complaints). What I can't adapt to is the complexity of the system and the cost and inconvenience of maintaining the brake components. I also don't want to take a chance on failures in such a crucial system.
