It occurred to me this morning that we can look at pocket calculators as an example.
I saw my first pocket calculator in 1972. As I recall, it cost $89, which was a chunk of change back then. All it did was add, subtract, multiply and divide. It had red LED numerals.
Today you can still get a pocket calculator that only adds, subtracts, multiplies and divides. And it has the superior LCD numerals. It costs a dollar at Walmart. My recent job required us to have a calculator with us at all times. I and others used to pick up a number of these to make sure that we were never without one.
So even though much fancier calculators are now available, the market still exists for the basic model. And at a buck, who can turn it down?
