Yeah, still not with you there.
I am but a simpleton and you may not have the desire to explain this one out.
I live in the universe with my real-life statistics, I still currently have a late 2009, 2010, 2011, 2012, 2013, 2015, 2017, 2019 - 27" iMacs. With the 2009-2011 models being quite a bit heavier and going on a decade of use, have not experienced any physical issues.
Having hands on with multiple machines using them in my day to day personal and professional world, I am still not putting together where a product around 3.4 ounces is going to in anyway cause a failure of the hinge system on this mac.
I am completely sure someone has had an issue with a hinge but I am not one of those people across this many devices over this amount of time making it, for me, a non-issue.
TETO
either way. Ordered a second for my home iMac. delivering tomorrow.
