I still use my 2009 27" iMac as a screen for my 2017 MacBook Pro.
My 2011 MacBook Pro was killed by Sierra last month - but I
was using it since 2011 with 16gb Ram and a OWC 1tb SSD.
My daughters 2011 21.5 iMac is running strong - I upgraded it
to 16gb ram and a 1tb SSD a few years back.
At $3k a pop I'm not treating my Macs like a iPhone - there is not need
to replace them every three or so years. There is plenty of reasons to
run them till they die.
