I agree with Chess to some degree, but I think it's not a good idea to compare cassettes, etc, with what's happening today. The computer chip has changed everything. Technologies change MUCH faster today than they did just ten years ago. I don't think you'll find things sticking around as long as you used to. The rapid rate of change in computer chip technology, and capitolism will continue to push newer and better things out at a very fast rate. I think the days of a technology like LP's being around for decades is long gone.
