The fact that I bought all my machines used (and mostly on sale), and that not one of them is general purpose, id est, I bought each piece of hardware with a (more or less) concrete idea of what would be its use case. For example, my machine acting as a file server is way bigger and faster than my desktop, and I have a 20-year-old machine with very modest specs whose only purpose is being a dumb client for all the bigger servers. I develop programs in one machine and surf the internet and watch videos on the other. I have no use case for VMs besides the Logical Domains I setup in one of my SPARC hosts.
