The article mentioned 10 things, namely: DVDs, home telephone service, external hard drives, smartphone also-rans, compact digital cameras, newspaper subscriptions, CDs, new college textbooks, gas-guzzling cars, and energy-inefficient homes and appliances. Some of these, I agree, but for some, probably not.
Well, I understand the DVD argument. Especially for me, I rarely have a movie in which I would want to watch it again and again. Perhaps The Fountain, but not a lot of other titles. And yes, Netflix is so convenient, just have a subscription and the movie will get to you through the mail.
I also agree that home telephone services can be obsolete. Everyone has a cellular phone nowadays, and the home telephone service just is useful if you have an answering machine. But the cellular phones have answering machines as well. If you simply do not want to pick up, then don't pick up. Self-discipline is necessary. Just because it rings, doesn't mean you have to pick it up.
I do not agree with the external hard drive argument. Yes, online data storage is cheaper, IF you compare the monthly subscription fee with the cost of an external hard drive. I have a 320 GB external hard drive, I paid less than 100 USD, but it was a one-time fee. Besides, I have the comfort that I do not need an Internet connection to access my files, and also the security that there wouldn't be a smart-ass hacker who could access my files because it's stored in a server somewhere in the planet.
Yes, I also agree that newspaper hard copies will be obsolete sooner or later, but perhaps not in 2010. There are still people who like reading their news on paper.
CDs will be gone. I myself use Internet radio and online music services. The last time I bought a CD was when I wanted rare music, when I wanted music from West Africa or the latest album by Tiziano Ferro.
Looking back, there are several things that the past decade had that we don't have anymore. Remember the Betamax and VHS? Analog television broadcasting? Paper tickets for airlines? Modems? I am pretty sure there are more stuff along these lines, but I can't access my memory for some reason.
