You're wearing a VR headset, so the visual UX of keyboard and mouse can be 3D anything. The keyboard and surround is all multitouch. The keyboard is n-key rollover - feel free to chord. The mouse is tracked in 3D. It's also on a motorized arm, so it has force feedback, and you can leave it wherever, or have it move itself. You have two of them. Your hands are tracked in 3D, so feel free to gesture, and to interact with the visual environment. If you value the fingertip feel of your keyboard, you can stick with fingernail vibrators. The mouse surface is variously pressure sensitive. The mouse surface is vibrator chips. The keys are covered with vibrators. The keys are multi-axis pressure sensitive. Your palm and back of hand are covered with vibrators. The headset provides a high-resolution soundscape. The headset tracks head and gaze. Any screen is notional, as the headset provides high resolution content with any apparent focus depth. The keyboard is on a robot arm, so you can stand or pace - just ask, and it will be at hand. For some tasks, like sorting piles of objects, you might briefly prefer a different interface device. Much of that is current-ish tech. Though painful to gather and make comfortable, given a dysfunctional market for such. Contrast the available design richness of phone vs desktop, interface and apps. Imagine desktop absorbing lessons where phone is better. Now try to imagine the design richness available to desktop vs something, where something isn't pretending to be a half-century old terminal emulating a manual office typewriter.
