Just fyi the law doesn’t make the batteries replaceable like on old phones, where you had to pop the entire back off, but just reasonably replaceable, meaning an end user with normalish tools (they don’t specify which afaik) should be able to open it. I imagine we will see thin designs like the iPhone Air where all the non-replaceable parts are in a plateau and the battery is easily reachable with a bunch of screws and maybe some prying. At least that’s what I hope for.
