Linux on laptops is like a disease. It's rare that everyone gets sick, but it's bad enough that many do. Even at Red Hat, where the employees collectively know more than anyone about making Linux run on laptops, internal mailing lists were often full of gripes about issues. If it wasn't the Big Three that I already mentioned, it was fans running constantly and batteries being sucked dry, switching monitor resolutions or dis/connecting a second monitor leaving things in a weird state, the utter impossibility of getting trackpads to work as well as they did under Windows/MacOS, international keyboard layouts not behaving properly, camera remaining locked when it shouldn't, and so on and so on ad nauseam. If you never hit any of these then good for you, but I can say with absolute confidence that such an experience is exceptional.
