Jack Purcher at Patently Apple has pointed out that Apple has been awarded patents for a notebook that uses two displays: one where you expect it to be, and one where the keyboard would normally be:
The device presented in Apple’s patent figure below illustrates a dual display notebook that eliminates a physical keyboard or Trackpad. This way the second display could also be used as a sketch pad, gaming controls and more as discussed in past patents.
Apple notes that in one version, a hinge is permanently holding the two displays together to form a new kind of MacBook.
In a second or alternative version, Apple notes that the hinge could be designed with magnetics so that it becomes a classic 2-in-1 device or second-gen iPad Pro so that the upper display could be detached and used as a standalone iPad.
I hope that falls into the “Apple patents everything it can think of” bucket, and not the “this is a thing that may actually ship” bucket. Yikes.
