Having worked at an independent PC repair shop, there are a lot of people who would rather keep using their old 6+ year old laptops and have SSDs installed in them than go out and buy a new laptop. Yeah there are cheap ones for sale, but they're underpowered, have regular old HDDs, and only 4GB of RAM. Plus, now they're coming with Windows 11 preinstalled, which will annoy a lot of people who are used to Windows 7 or 10.
Currently work at an independent PC repair shop, and can confirm this.
It's not uncommon for us to get a machine which is limping along on Windows 7 for the 15th year in a row, add an SSD and reinstall 7, 10, or rarely Linux Mint depending on how stubborn the user is on not upgrading to 10 and how open they are to change.
Windows 10 is like 6-7 years old now no? This cannot be representing the majority of the market. How much of the market actually upgrades their OEM pcs?
