A lot of very interesting comments above. Manufacturers charge what the market will bear; too much and they go belly-up; not enough and they don't have the resources to survive tough times and develop new products. I esp. liked Uru975's comment:
If simplicity also meant inexpensive it would be nice. All to often something that is very simply made, almost elegant, is a work of extreme craftsmanship.Whoever actually wrote the line attributed to Twain- "I'm sorry this letter is so lengthy but I didn't have time to write a shorter one" knew what he or she were talking about it. It is certainly easier to put a bandaid on a problem (more parts, more complex circuit) than is is to design the problem out of the product. Simplicity is the "ne plus ultra" of any design or creation. It should be as simple as possible in order to achieve the designer's intent; no simpler and most certainly no more complex..
