You may have to wait a while if you want a Mac with an E Ink keyboard. Wall Street Journal tipsters understand that Apple wants to make Sonder's e-paper keys a "standard feature" on MacBooks, but that it's aiming for a 2018 launch. Don't expect to see anything at that reported October 27th event, then. At least we're getting a hint of the functionality. As you'd expect, E Ink would let your Mac use "any" alphabet, along with special characters and media editing shortcuts. You could write emoji more like you do on a smartphone (where you replace the keyboard with an emoji picker) instead of using a keyboard shortcut and wading through an on-screen dialog box.
