Dealing with all the disposable waste that we produce is an important way of being green. Any way you can eliminate purchasing something you immediately have to toss is a good thing.
I think what we need to tackle as well is things manufactured to be obsolete. One of these things is lightbulbs. Fortunately, there is good news on that front, according to the blog, Inhabitat. According to this post, Panasonic’s New LED Bulbs Shine for 19 Years:
Despite lasting longer and being more efficient than both incandescent and CFL bulbs, LEDs haven’t caught on because of their sky-high prices. But now Panasonic wants to bring LEDs to the mainstream — at least in Japan — with a 60-watt household bulb that the company claims can last up to 19 years, or 40 times longer than incandescent bulbs.
Not only are they long lasting, but they are LED. This is a good thing.

With the rapid development of lighting technology, this light bulb may be functionally obsolete much sooner than 19 years–maybe in 19 months! A victim of a rapidly changing technology. This has happened with digital cameras, cell phones, etc. Can you image keeping your first cell phone for 19 years?
That’s an excellent point. Digital technology does change very fast. However, other technologies, such as battery technology, does not change as fast. I think the change rate will vary with the technology.
That said, I still think you have a great argument for considering the benefits of any technology that can last 19 years. At the very least it should be recyclable/reusable.
