it's really an ergonomic nightmare that doesn't improve on the current design.
The keyboard would have to be wireless to be functional as no one in their right mind would sit as close to the screen as would otherwise be required. And, if the keyboard is removable and wireless then you're left with a massive "chin", for lack of a better description, that is not aesthetically pleasing when the keyboard is removed and takes up valuable real estate on your desktop. As an example, currently I have a disk drive sitting on top of the bae of the stand so as to maximize desktop space. Others no doubt use this space to store other things. There's also the aforementioned issue of adjustability of the screen angle that would appear from the patent to be somewhat challenging and/or lead to the use of the types of materials in the Galaxy Fold, in the upper "chin" area, that are prone to scratches and other damage over time.
The size of the stand / component enclosure also appears to much bulkier than the current design of the stand and again will take up more desk top real estate than the current model.
Ergonomically and aesthetically this is a step backward imho. I think its safe to say that John Ivy wouldn't approve.
