Depends on who you’re asking. My 2012 Thinkpad is on the latest Windows 10. It works very well with its SSD and it is really quiet (new thermal paste). Meanwhile, my 2011 MBA cannot even get GarageBand from the App Store because its OS won’t upgrade. Otherwise it’s fine...

Well sure it depends on who you ask, but though it’s just anecdotal, both you are examples that “obsolescence” may not be that big a driver.
