The new model which I am looking forward to is the Lenovo Yogabook 9i which is two displays facing each other where one can have a keyboard on it, or one can connect an external keyboard and have a dual-screen setup:
I'm hoping this form-factor becomes popular enough that someone (Samsung?) makes a version which supports a Wacom EMR stylus (not wild about Wacom AES, though I may have to break down and accept it).

And a few years back they had a laptop where the keyboard was an e-ink screen.
