Whaaaat? Laptops with integrated graphics are the vast, vast majority of personal computer sales. That's its major use case. The one that almost everyone with a laptop has.
Major bias here. That being said, among me and my peers I don't know of anyone who has a (non-apple) laptop without a dedicated graphics chip.
What about laptops, tablets, smartphones, and "internet of things" devices? It is definitely a mobile-first artitecture, no doubt about it, but you're selling it short.
