I had a 27" Sony Trinitron TV and it was incredibly heavy for its size! Very awkward to move since all the weight was at the front. A friend had the next size up (35" maybe?) and it took two people to move it.Flat screen CRTs were very heavy due to the amount of glass needed for strength to create the vacuum. iMacs weren’t as heavy as the screen was more curved.
I remember flat crt TV I had once. Crazy heavy monster.
