Foldables are life changing - everyone I know who's got one, doesn't go back.
It's all the benefits of a tablet with the weight/thickness of a cell.
Example: maps shows both the map and listing detail.
Example: messaging/email apps show the message/channel list and the current message
Example: virtual keyboard has plenty of space for punctuation, emojis, etc.
Example: games and multimedia are perfectly pleasant to view, even for hours.
Example: I used the remote-control app to take photos from my Sony and Fuji cameras, and the live preview was large enough to easily check for tack-sharpness, which is hard even in the camera viewfinder.
Anecdotally, everyone I've seen with a foldable has gone back.
