Desktop PC hardware is sufficiently modular and easy to upgrade. It would be nice if upgrades were add-on rather than throwing away the replaced module(s) but HW changes so fast it's almost never worth it. Software could be improved to make things longer lasting such as make clean install trivial with good separation of user vs system data. I recently added an SSD and made my old HDD the G: drive but the new instance of Windows on the SSD did not consider the new SSD userid with the same name as the old HDD userid to be the same user and so accessing the old files became a file sharing nightmare. Also the old HDD drive started taking forever for reboot file system checks and I had to just disconnect it. So now I am wading through all my old backups trying to figure out what is what.
