I found a 60-watt replacement CFL at Dollar Tree this past weekend. It's not in a nice round shape like others (two small, straight tubes), but for a dollar, I can't complain. Since they last upwards of 5 years, any CFL replacement will have to be cost-effective.
Plus, whats the incentive for producing bulbs that last 60 years? What kind of company can survive when they only sell products once every 60 years. Sure, there's the long ramp-up time, they can't replace all bulbs at once. Then there's always new installations, and broken bulb replacement (which will be far fewer than vacuum-bulb incandescents and crystal CFLs), but seriously, we'll start a big new industry, and 20 years from now, once everyone has these new super bulbs, 90% of the new businesses will go under. And don't give me any "light bulb service will replace light bulb income" B.S. It doesn't work for free software, it won't work here.
