When we lived in earthquake areas, certainly.
Our last one was a hand me down rear projection affair that rolled, weighed about 200lbs, was 5 feet from floor to top, 4 feet from front to back, and 6 feet from side to sid. There was no "pulling" it over on someone!!! It was a VW bug sized monstrosity. (So happy it died).
Now? Not yet.
But it's about to get bolted to the wall, once I can cut some drywall out. LOL funny thing about reeeeeeally thin TVs (it's half an inch thick, and weighs maybe 10lbs), the PLUGS (for the xbox, dvd, etc) stick out twice as wide as the TV! No way to get it on the wall without cutting out drywall. And to attach it to the wall, well, it will be attached to the wall.
