So my idea that could double the power of the Nintendo Switch ( and might make it able to do 4K at a really good frame rate ). Is actually quite simple. If Nintendo made a special docking station that lets you put two Switch's in and it then uses both of them together to improve performace.
It does sound simple and would be a great feature. Even if you don't by two Nintendo Switch consoles you could still use it by combining yours with a friend.
