My presumption based on my experience in manufacturing is that manufacturers reduce costs by having one set of keys & bezels if possible.

More accurately I should have said that they imply install the same components like the keyboard on all machines regardless if it's a walkup or drive up unit. This way they can reduce inventory needs (1 keyboard type in inventory instead of 2) and help to reduce costs. <img src="/forums/images/graemlins/kewl.gif" alt="" />
