I hate to say it but calculators still litter the desks of many of my colleagues and are in use regularly by them on a daily basis. As for the death of vinyl and turntables, they are doing very nicely through the musical puritans who reject digital recording, those with big vinyl collections and the DJ crowd. I notice that while the slide rule was on the list, the typewriter was not and the increasingly pressurised floppy disk didn't make the list. I still like floppies but they have a niche role in my life. As for the slide rule, I still have my flight 'computer', which is in all essence a rotary slide rule and still very fast and accurate, without any battery problems.
As to pagers, there are those still using them in environmentally sensitive (hospitals, oil & gas, hotels) areas.
Modems, don't write them off either. I live in a developing country and not only are they useful for internet connections they are also a great way to send faxes without needing a fax machine. They might be old but they still have a role.
