My computer is an Apple 12.1 inch Powerbook G4 1.33 GHz, vintage 2004. In other words, it's old and not terribly fast. I bought it in the spring before I went to college and I have owned it ever since, nearly seven years.
As I gaze around my room and see how much junk I have, I also appreciate all of the valuable quality things that I have. Things that could very well last longer than I do. For example, I have a 1930s Royal typewriter that is in almost as good of condition now as when it rolled off the production line over 70 years ago.
I feel that quality stuff is totally the way to go when buying anything that will be used multiple times. For example, I bought and broke several $8-18 watches before I finally bought a $50 watch that does everything I need and it has lasted longer than any of those previous watches. My computer is a prime example. At $1,600 it was a huge expense when I bought it but provided it makes seven years that is an average of $20 per month. Considering that it helped me through two engineering degrees, thousands of hours of work, and that I pay way more than that per month for my cell phone, I can't imagine a much better deal.
Finally, buying quality is environmentally friendly because you buy less. Had I gone through three computers in the time that this one has lasted me how much of those computers would be sitting in a landfill? Similarly, using ceramic plates instead of paper or styrofoam plates entail a little bit of washing but nothing ends up in a landfill.
The same can be said for products as for time. Such as how I spend my time running. Running eight minute miles for 13 hours a week is great and I get into great slow aerobic shape, but seeing as how my goals involve running paces much closer to five minutes per mile, I need to run workouts close to those paces.
Just something to think about.
