Was thinking about the upcoming change from Win 10 to Win 11 recently and gazed on my TRS 80 Model 102 notebook computer which sits between my keyboard and my monitor. It occurred to me that upgrades were so much better in computer days of yore. All you needed to do was unplug all the peripherals (the mouse, the joysticks, the printer, etc) from the old computer, unplug the computer itself, swap the old machine with the new machine and hook everything up again. Your software was on disks (hard drives were rare in those days) and could be loaded when needed and your operating system was in ROM (no need for configuring or constant updates). Simplicity in itself. Of course modern systems can do much more than the old systems but still there is something to be said about simplicity and efficiency.
