I'm super excited to see them figure out/be comfortable with a detached Touch ID. I've wanted my watch to be set as a Touch ID, or my wireless keyboard for my mac mini, and historically Apple seemed like they'd only allow physically attached Touch ID. With this product, it looks like they're providing a Touch ID keyboard that's wireless. I'm very curious how that works logistically, and if they'll make the keyboards…
Because in this case you can replace the keyboard and keep it secure, which contains the Touch ID sensor.
