1. Integrated liquid cooling using special solution, cooling all components.
2. Complete modularity using special plugs, like pins are for CPUs, being kept in place with a different system than actual ones. Water cooling comes over all components that need it, using another modules. This means motherboard, display, CPU, GPU, Random access memory, battery, all modular. All producers use a single type of modules, so you can change any moment you want. Like this, you buy a shape, then fill in with every modules you need.
3. Under 6KG total weight
4. Usage of a different display, with entire human visible range covered, 450nits, and cover display that is impact resistant. and glass on the surface, with options for both glossy and matte (I would had preferred glossy for everything).
5. Possibility to buy a 3 display setup, using very slim display modules (5mm) and just have 3 display setup portable. Really wear-resistant hinges.
6. Enough GPU power to render 8K (for VR) at 60 fps ultra for all games.
7. Priced reasonably, for every user's needs. For example, a module should be 10% - 20% more expensive than the desktop counterpart, to be made a module and have everything, but not more.
8. Employ @Prema to make Bios for the 3-4 Motherboard options, to be sure that everything works best for power users! (If everything is modular, including motherboard, there should be at most 3-4 motherboards out there for performance laptops.
8. There should still exist very light, slim, and low power netbooks, or something, for people who work with office, and carry these a lot, and do not need the power. These slim laptops should still have enough power to watch videos at 4K, and play dota2 on medium FHD settings, but be more concerned about battery life, and comfort than everything else.
Yeah, if these boxes are checked (they will be sooner or later), we should all be very happy with laptops.
