its modular like a desktop pc. you can fix it and upgrade piecemeal instead of junking it, also like a desktop. if you are a gamer you dont need to be in that common situation where the cpu still holds but the gpu is already oooolddd that usually happens on laptops.
I know it's an absolutely banal nitpick, but I think it's unfortunately a revelation in the current laptop market that ~90% of a laptop stays good for a really really long time, and the other 10% can be upgraded piecemeal as the need arises. Obviously this was never news to the Desktop world, but laptop manufacturers got away with claiming this was impossible for laptops in the name of efficiency and portability.
