I still have my IBM luggable. I logged a lot of time on it.
After my dad retired he bought a motorhome and started a business as a consultant. He hired my mom as his bookkeeper and they traveled around the country until he got the last of it out of his system.
She taught herself how to use the computer and Lotus notes and Excel and Word. I remember when they returned from one trip and showed me their “big upgrade” - a 10-megabyte (megabyte!) hard drive. Up until then they ran the operating system off one of the floppy drives.
