About the only two things i could see that might need changes for it, are longevity of the connector (make it last more insertions) and maybe making it thinner for devices that don&#x27;t seem to want battery life in favor of being thinner&#x2F;lighter.<p>Even then it&#x27;ll still be a really hard sell because they&#x27;ve been improving the longevity for a half-century and it&#x27;ll be hard for something else to come up to that kind of ease and reliability.
