I frequently carry my laptops by the body one handed, which probably doesn't help. I also (used to) travel a bunch, so the laptops end up getting stuffed into and out of densely packed bags. In most cases though, the hinges are just badly designed. In one extreme case, the hinge's mount points on the case were all in a straight line in line with the hinge's line of rotation. As a peer post pointed out, just the stress of the lid's friction lock + 1-2 years of constant use tore the hinge right off the case.

The Framework has a proper cross-brace on the hinge, the hinge mounting points are metal, and I can inexpensively replace the case or hinge if either breaks after the warranty expires.
