I keep it for sending the thing in for repair or trade-in. Most other manufacturers don’t offer warranty repair in most cases like AppleCare does and they don’t offer trade-in. So there’s no point in keeping the box around.

I’m not sure anyone thinks about much of what the article presumes they do. Especially luxury and status. I seriously doubt anyone keeps a cardboard box for the prestige.

What an unusual article. Though it would be interesting to hear from someone who does keep product packaging for the reasons it enumerates. Could be eye opening.
