Graphic that just about explains it all:
I don't know if any folks remember, but decades (?) ago, Sprint had a "walkie-talkie" feature on their cell phones. I don't think that feature was ever "accepted" by the general public and it gradually faded away. Maybe it still exists; I don't know.
Based on the comments at the linked article, Applephiliacs would appreciate new laptops and/or desktops and less emphasis on mobile gadgets. Most important to me: the MacBook Air. And it's still available.
