Probable solution: deprecate keyboards, spinning it as antiquated technology that throw back to typewriters. Spin "the future" of laptops as keyboard-less laptops. Maybe try to position Siri as dictation assistant ala Star Trek "the future." Sprinkle in some "solid state" references too.
Build in a special keyboard jack, proprietary to Apple and offer a separate keyboard (sold separately of course) for those that must hang on to the past for only $699 or $899 if you want to be able to use capital letters too. Make SOME control on that keyboard essential so that no consumer can readily try to make do with a generic USB keyboard.
Keep the price of the keyboard-less laptop the same... or maybe raise it because it is helping to "force" us (clinging to floppy discs or horse & buggy) fools to "the future."
Make it so only an Apple keyboard can be purchased for it for several months, jacking up average revenue per new laptop sold. Stockholders love those increases in ASP and we consumers really don't care- we'll pay anything.
Rally the legions of fans to shout down anyone who offers any crits on losing the most ubiquitous input device that "just works" in favor of trying to make Siri work as a full "the future" replacement.
Spin "thinnest MB ever" because that's most of what we consumers care about short of "...but who makes the most profitable _________?"
Then, start planning the deprecation of the antiquated battery, screen, hinges, glass, etc so that eventually we can pay full price for just an empty box and more to buy parts separately to buy back functionality that used to come built in.
With each deprecation, spin "thinnest MB ever."
Record revenue. Max margin revenues. Zero repair liability for getting people to buy an empty box product. Geniu$$$$!
