Exactly. And I think even most casual users underestimate how liberating 4G/LTE streaming has been.
In 2011, before 4G arrived on the iPhone, I suspect most of us physically carried around large files. Holders for our CD collection in the car have been replaced by Apple Music and Spotify. Binders with our school notes are now kept in OneNote or Notify. We can retrieve photos and videos from a decade or more ago from the cloud that don't exist physically.
Next year, any profession or business that still has to deal with dragging around physical media because of speed and capacity limitations will start to see the light at the end of the tunnel. If Apple is not going to be a part of that solution in 2019, as a business or professional, it might not be a good business decision to pay a premium price for a device that will never be able to take advantage of the 5G capabilities that may be coming to your area or being deployed to areas you visit.
