Here in the mobile tech world, we absolutely love slapping labels on products, breaking the market down into categories. Some of those are clearly defined: While they come in all sorts of shapes and sizes, no one’s really debating what counts as a “foldable” smartphone. But others have been far more nebulous — remember 15 years ago when “phablets” suddenly descended upon us, but no one quite seemed to agree on where to draw the line between those and regular smartphones?
Some of those ambiguities resolve themselves — with phablets, at least, phones in general have grown so large that the word has lost all meaning — but others have really managed to persist.
