I don't feel old enough to say this, but here goes ...
I remember being excited by the upgrade from my manual typewriter to an electric IBM typewriter in the 70s, and then ecstatic when I could finally afford to buy an IBM 'self correcting' golfball. It was a joy to be able to lift a typo from the page without having to retype the entire page to make it look perfect.
The fax machine was one of the best inventions ever ... take it from someone who used to have to type then fold and feed the skinny telex tapes into the annoyingly tiny slot on the side of the telex machine.
I remember being told that having a computer would mean I'd have a 'paperless desk', and I distinctly recall how my very first laptop in 1991 felt like a ton of bricks.
I'll be honest. I would happily return to using an IBM 'Correcting Selectric II' and a fax machine. I liked those days. I rarely received junk mail, and my desk had less paper on it before it became so easy to print everything without any real effort.
