2021 MacBook Pro has a replaceable battery

From a moderation point of view the logic was: both threads were active (and even on the front page IIRC), and they were about the same story, so I merged the later submission into the earlier one. Generally speaking, giving priority to the first submitter seems fairest.

One twist is that the later submission had the original source while the earlier one didn't. When there are competing concerns like that (one post earlier, one with the better source), we have to decide which takes precedence. Usually I go with the earlier submission and change the URL, but I don't know if we're that consistent about it. In this case it ended up working out that way, but only because I didn't realize until later that the one article was just reporting on the other.

Users sometimes find it annoying when their submission is the one that 'loses' in a merge or whatever, but (a) it evens out in the long run if you keep posting interesting stories, because the dominant variable here is randomness; and (b) your submission still got hundreds of upvotes.

My 2013 macbook air is plenty slim and light but changing the battery is just a matter of undoing a bunch of screws and clipping it in. Takes <5 min. I'm not sure there are any real world advantages from glueing the thing in?
