Bigger is always better in computing. Just maybe don't try and tell that to the SFF guys with their Fractal Terras and neat cable routing. But in these terms the 18-inch gaming laptop is a desktop replacement beast; it's the largest form of laptop and a crazy idea that pushes against the idea of a portable computer actually being portable in the service of higher TDPs and more fans.
I mean, it is still portable. But only in the way that your desktop PC is portable if you pick it up and put it down somewhere else.
