I'm a little skeptical when someone says they have built a better mousetrap but nobody wants to buy it. The reality is that in the manufacturing business, there is extreme competition and anyone who can create a better product for the same price
or lowered operating costs, gets the business most all the time.
This is the reason we no longer see the major airlines using DC-3's for carrying passengers or Intel 80286 CPU's in our computers
. Somebody built something better.
