Whereas any dating of when my last desktop build was would be deceptive because they're replaced piece by piece. The closest occasion I can give is when I went from one to two desktops, but even then half the guts of the one I had before went into the new case, and were replaced in the old case with new purchases.

I mean, I've met people that only wear underwear once or twice before throwing it away, too, but I wouldn't say that's normal. People would generally rather replace a drive, processor, ram, or screen than spend 10x as much on an entirely new system. They don't because the manufacturers make that option difficult or impossible.

People didn't love VCR/TV combos, and people don't love this. Manufacturers love this.
