Any time you buy a piece of computer controlled hardware, you are usually frozen to using the operating system it was designed for. An OS upgrade usually causes the hardware to malfunction.
This includes cash registers, laboratory equipment, home control systems, and music studio equipment.
It is time to permanently end this mad rush to upgrade. The only way to do this is to require support for all OS versions for at least 20 years (the length of time of long-term scientific studies).
