You stated that you will never own one. If you are not a customer for the product (for whatever reason: from physical to medical to something else), nor will ever be, and have never used anything in the category, I am not sure why you think your opinion about its feature set matters? As a non-user, you are speculating about what others who actually use this tech will want, with no information. A perfect example of this lack of knowledge is your original comment in which you did not even know that one could operate the device connected to power.
