@jeff @tychotithonus I mean, it's actually not good advice except for "something will have to change." You don't just use a trackball because it looks cool - alternative input devices are usually chosen because of physical issues with the default input. If you need to keep your wrist at a certain angle because of pain or control difficulties, changing to an entirely different plane will not be the solution. Giving up computing, or getting a different, less hostile system, will be.
