"My" slide show article? How is it "my" slide show article? I didn't write it and I've gone on record in this thread stating that I carry an EDC flashlight(s) [so obviously I hardly consider them "obsolete"] in addition to my phone. Please instead refer to it as "the article you thought some here might find interesting, even though many of us might not agree with all of it" or simply "the article you linked to".
It is an article clearly written specifically to invoke discussion, thought, and public commentary, as far as I'm concerned, since it has no researched data backing any of the listed entries' actual sales or usage figures. Did you catch this part, which comprises nearly a third of the entire written text?:
"Do you agree or disagree with the items on this list? Cast your votes, and tell us in the comments if you still use any of these gadgets, as well as if you think there are other devices smartphones are putting out of business."
