My point is that if something goes wrong as things often do with laptops, it's very difficult to replace it when it's all on one motherboard. I've got an old Thinkpad which is a beast and mostly works, but it has a problem where the power supply stops occasionally and beeps at me. If it were a desktop I could simply replace the PSU, which is modular and standardized. Such is not the case with laptops, and there's very little interoperability except for some components. Since the golden era of ThinkPads, most machines have gotten more and more disposable and locked-down, with soldered-on memory and other longevity compromises to reach a smaller form factor.
