This reminds me of one thing I don't understand - keyboards that tilt up towards you. I find that wrists elevated and flat or slightly down is most comfortable, and the tilted keyboards cause me to bend my wrists up in an awkward way. Who decided that this was a good idea? The cavity desk sounds like a more extreme version of the genal posture I find most comfortable.
