A 12.22 HuffPost piece has listed 20 things that have either disappeared or are on their last legs since 2000. Texting has overtaken phone calling but it will never disappear, but travel agents are all but gone, of course, and so are bookstores (fading), phone sex, maps, print classifieds, dial-up internet, encyclopedias, CDs, landline phones, film cameras, yellow pages, address books, printed catalogues and fax machines.
I for one am fine with the separation between work and personal hours have completely dissolved. Buy watches will always be cool in my book, and hand-written letters should never disappear.
