I think you nailed the purpose and business model right there: Apple creates a folding screen only MBP and a huge suite of proprietary accessories to support it that must be bought to use the all-screen-Touch-Book-Pro to its full. So they make money off of the $4000 price for the all-screen-Touch-Book-Pro... and they make scads more money on the all new bluetooth keyboard, mice, port hub, pencil, ear buds, Gen 3 Vision Pro goggles, all new MagSafe charging system for screen / keyboard / mice / hub / pencil / ear buds / Gen 3 Vision Pro, all-new Apple stand to support the the All-screen-Touch-Book-Pro and its gear, a special Pro-level cloud storage service, a special Pro-level cloud-based AI functionality that lightens the on-device OS load,....Will come with two ports on the base model /s
Joking aside, I can imagine all the proprietary accessories (keyboards, mice) that would come with this.
So that by the time you finish kitting this thing, you are in for $8,999.52 plus the monthly services fee. Oh, don't forget the additional $500 for the all-new all-screen Touch-Book-Pro Apple Care plan to protect all of that glass real estate. And the $500 Apple polishing cloth to wipe that glass. And the $500 nano-texture coating on the glass.
Make that about $10,500.52 to kit this thing and bring it home.
Apple's new product here is not the all-new all-screen Touch-Book-Pro. It's the all-new magical Apple up-sale that makes you want to fork over large sums to get the next new Apple eco system they will make you purchase to get the all-new all-screen TBP. Apple's new #1 new goal and #1 new product these days is cash-flow accretion -- the #1 new goal is not awe-inspiring WOW-inducing product dev. Actually inspiring product that WOW's customers and thoroughly upsets competitors might be at number 22 on the list of Apple priorities.
I am saying this part very quietly after all of my complaining... if it turns out to be awesome, where do I line up so that Apple can take my money?
