I think it's reason #4. I bought a PC 12 years ago, the only upgrade I did was buying an SSD, and now it's being used by my father, who's perfectly happy with it, because it's fast enough to check mail and run MS Office. My current gaming PC was bought 4 years ago, and it's still going strong, I can play most games on high settings in 4k (thank you DLSS). I've noticed the same pattern with smartphones - my first smartphone turned into obsolete garbage within a year, my current smartphone is el cheapo bought 4 years ago, and it shows no signs of needing to be replaced. ok I lied, my phone is only two years old, but what happened is that two years ago my phone experienced a sudden drop test on concrete followed by pressure test of a car tyre, and it was easier to buy a new one with nearly identical specs than to repair the old one.
