“To reduce the size of laptop, the keyboard have 16mm key pitch.”
Shun Ikejima built a laptop out of a Raspberry Pi Zero W, a 7 inch screen and 48 Cherry MX switches. The Pi can’t suspend and boots slowly, so he wrote bare-metal code to get it up in under 5 seconds. The goal is a laptop that can design its own successor in CadQuery. Apple has a few thousand engineers and still ships a notch.
