You can trace the iphone back to, concretely, the newton but even further back if you check out the concepts that got them to the newton. There is a 1997 book called 'Apple Design 1997 The Work of the Apple Industrial Design Group' that shows a ton of concepts and a few 'communication device' concepts (video and audio phone integrated computers). Sadly out of print, and quite expensive for a paperback 'coffee table' style book https://www.amazon.com/Appledesign-Apple-Industrial-Design-G...
There is a cheesy movie from Tom Cruise, Minority Report, whomever takes those displays to market, finds a scalable profitable way to produce them, finds enough courage to resist status quo and find massive product market fit, will be the next Jobs or Musk. Idea wise, everything literally was on either Star Trek or on Star Wars previously. I know these personalities are not exactly likeable but we'll keep this conversation for the next simulation of the universe with different parameters...
What if we think those displays as VR headset alternative? I feel it could be hugely helpful doing surgeries/repairs don't you think? Direct brain connection means too many cmd-z's for me.
Some pictures from inside, including one concept integrated with a telephone handset: https://twitter.com/jamesthomson/status/798542140435480576
