Yes.. try moving that 36 inch Sony Trinitron from the car inside the house.. weighs 200 pounds+ IIRC....you need at least 2 strong people
They were fun monitors - we had a lab full of them, they would degauss on startup, and the degausser would induct into the monitor next to it (and a little bit into the monitor after that).
Don't let me get started about fixed frequency, X11 modeline guessing (wrong of course) and needing a second monitor to even get back to the original config.
It's possible they also had more glass than typical for a 21" monitor, I don't recall if they were any flatter than the Viewsonics or not.
I wish I still had one around, just to degauss it occasionally.
