That’s incredibly difficult in compact form factors. Modular frames and connectors would also add weight, etc. So far you can basically replace the SSD and spare parts like the joystick. But I’d certainly like to see them try. We’re not going to see them make the CPU or GPU replaceable, but I’ve seen stuff like electrically activated glue for attaching components like screens while keeping it repairable because it’s easy to release with electrical activation again. Would be cool to see Valve make use of stuff like that.
