LED lightbulb replacements - long-lived and low-power

ThinkGeek's carrying a line of simple, low-priced LED light-bulb replacements. They last ten years and draw one thirtieth of the power consumed by incandescents. I think the only downside here is that something that's this long-lived is bound to be obsolete long before it's burned-out. That's the green paradox: green manufacturers focus on long-lived tech because that's good for the landfills, but they also do such good R&D that the next generation of products is often miles better and miles longer-lived, which presents the dilemma of throwing away green technology before it's used up in order to replace it with wildly more efficient successor technologies.
