Google does just that (Android and Chrome OS). *NIX hardware vendors used to do just that for Unix. Silicon Graphics and Sun for example. What you need is large hardware vendor (like Apple or Google) that takes Linux and really polishes the userland, UI, hardware drivers and curates and integrates all software. All drivers work for their hardware and UX as well for select number of devices. If the software is free, you need hardware sales because all that is expensive and tedious work. It takes large teams to pull that off. Even big companies like Dell or Leonovo don't see enough profit to do that. They put in some money and resources but not enough to go the last mile. Small Linux companies like System76 don't have resources.
