<i>People do not pay for technical advancement. They pay for solving their problems.</i><p>Yeah, I get it. My point was that it isn't easy to find something people are willing to pay you for, no matter how simple that sounds.  Also, technical advancement typically involves making something difficult and costly, easy and cheap, so I thought it was reasonable to assume that people would pay for it. I was either wrong, timed the market wrong or failed in my marketing efforts, which is admittedly not my strong point.
