One wonders if the patents have any bearing on the next SP model. Although I'm not sure it needs a height reduction!
Microsoft has patented several related technologies which could come to the future Surface Pro 7. One of note happens to be for a thinner and redesigned Type Cover with haptic feedback. This patent suggests that the Surface Pro 7 could have slimmer bezels, a lighter profile and a reduced footprint thanks to a circuit board directly that is etched directly into the touchpad of a keyboard. It also hints that the overall height of the next Surface could be reduced.[…]
A second patent also supports the wild claim that the Surface Pro 7 could come with a reflective touch display. That could mean you’d be able to write on both sides of the device. […]
An August 2017 patent shows that Microsoft is considering altering the hinges supporting the kickstand so it could open up and close more easily. […]
Though the thick bezels are often cited as a reason for comfort in tablet mode, it has become a bit ugly by 2019 standards.
