They said they are laptops, they’re not PCs. “PC” is a Windows term, traditionally. So a Chromebook is quite literally not a PC. You say they can boot Windows, so that makes the argument a bit less solid, but it wasn’t sold as a PC, then. In my opinion, continuing this line of argument is kind of silly, the point is that most decent consumer laptops that come provisioned with Windows still have replaceable storage. Or maybe I’m just very lucky and all the laptops I’ve purchased did. Even my mini-PCs like Intel NUCs have replaceable storage.
