Case in point #1:
Probably 10 years ago, I bought a compact (at the time) CD boombox for my desk in my office so I could listen to the radio and to my holiday CDs. It works great for my needs. As I was lugging it to work to put in my new office the other morning, I realized just how HUGE it really is. The remote control that comes with it is larger than most MP3 players these days. For a moment there, I vacillated: was it worth hauling this piece of antiquated equipment into the office? Wouldn't I much rather have a tiny MP3 player and stereo sound dock for it? Sure, maybe. It would take up less space. But, why bother when what I have works just fine?
Case in point #2:
For years, I used an old Nokia cell phone (see below, left) that my kids affectionately called "the brick." It was rather big and thick and didn't have any bells and whistles. No camera. No email. No MP3 player. No Internet capabilities. But, it placed and received calls just fine, thankyouverymuch. And, quite honestly, it was really all I needed.
Not only is upgrading electronics unnecessarily an expensive proposition, you are also faced with the problem of disposing the old items in a safe, ecologically friendly manner. I'd rather have my 10-year-old boom box sitting on my shelf playing music than sitting in a landfill somewhere, or even sitting in my garage gathering dust. And, I am still looking for a way to dispose of my old cellphone in a responsible manner.
