For instance, would you carry an iPhone the size of a shoebox if the rest of the space was a battery? Would you even be willing to carry one of the 80s phones that had a satchel?
Interesting. I was thinking of having iMessage/Messages, but I forgot most of the world uses Whatsapp to text, anyway, so that function does exist.
As far as calls go, I’m surprised by how unappealing the idea was to me. The amount of spam calls I get would probably kill my relationship with computers, honestly. For normal calls, I’d definitely want a headset of some kind rather than built-in mic and speakers, though I suppose a purpose-built laptop would include better audio equipment.
