Users on here tend to be those with more demanding apps but even so $5000?
I bought my wife a new PC (processor unit only, re-used monitor etc) $400 and it's overkill, not used for much more than Office suite, basic photo edits and browser (but a lot of disk, she never deletes anything). She could have stayed on W10 but the machine was getting flaky. Sure Linux can extend PC life but no way would I risk moving my wife to it, and in any case her W10 hardware was old, slow and had been exhibiting problems despite upgrade to SSD a few years ago. She doesn't like change so being the go-to authority I thought I'd be in for a difficult time and was prepared for all kinds of gripes about W11 being different but she took to it very quickly and acknowledged that the new box is much faster. I set her up with a KVM switch so she could switch back to the old box if needed. She tried it but after a couple of days found she had no further need for it.
I'll be spending a bit more sometime soon for myself but still a long way shy of $5000. My replacement cycle is usually 5 years and I understand that's around average for desktops, and quite high for
laptops (the old PCs are still fairly good spec so not trashed but go to a good home). When I had a proper job my employer's policy was 5 years life for desktops, 3 years for laptops (The implication for anyone who was not given a timely replacement was that they would be being made redundant soon so let's not waste money on a new PC!)
In my experience keen gamers like to upgrade quite frequently will have moved to TPM2 equipped PCs at some time since W11 was released (almost 10 years ago) although they may have stuck with W10 until the general consensus was that it was reasonably stable.
I'd not be surprised if a lot of non-tech W10 users have W11 capable PCs but are wary of upgrading the OS (or don't know how, or don't even know their hardware is good enough).
