I have a love/hate relationship with the Eve PF / Surface Pro form factor. I love the weight and the way the keyboard detaches to make a tablet; and I hate the way it's floppy, top-heavy and unbalanced compared to a clamshell laptop when the keyboard is attached.
Form factors like the Surface Book's is nice but also flawed in the sense that the base needs to be heavier than the tablet portion to feel balanced as a clamshell. So the overall device will always be heavier than a Surface Pro form factor device, assuming we keep the battery specs a constant.
Would it be possible to invent a Display Cover?
I'm assuming the pogo-pin port can carry the video signal. When the device is used as a clamshell, the tablet's screen goes black, the touch panel stays hot and registers the key presses and gives you a (very) large glass track pad. The Display Cover's hinge has enough friction to hold the display at any angle but not too much that opening the 'lid' with one hand doesn't topple the device. The screen in the Display Cover isn't a touchscreen, to keep battery drain on par.
Not shown in the photo mock up below: the mechanical keys are hinged as well, folding down from the Display Cover. So removing the Display Cover magnetically removes the keyboard at the same time. This is for people who like tactile keyboards and to allow having only one display running, again to keep battery life on par. (Had the Eve used an OLED display, I guess we could have Tron-like soft keys (Yoga Book style) while staying on par...)
With a convertible clamshell/tablet that has the same volume and battery life as an Eve PF / Surface Pro, an uncompromised experience in both tablet and clamshell mode, it would be love/hate no more.
(If, and I think this will be quite likely, the pogo pin of the Eve PF doesn't support video signals, perhaps this could be the basis for the next Eve device. In the same way Microsoft made the Surface Pro and then the Surface Book, Eve could make the PF and next the Pyramid Book )
