Desktop/Laptop Screen Orientation
One obvious difference when we design for desktop versus mobile is the orientation of the screen. Laptop screens are typically 16:9 or 16:10 screen ratio, which are horizontally oriented.
This has an impact on how applications have been designed over the last few decades - so was the software a driver for hardware changing form, or was it the other way around?
So why did we go from a vertical orientation, to a horizontal one?
There is a Quora question here but doesn't explain why it happened, just the history.
As a follow up, are desktop/laptops design ever likely to revert to a different screen aspect ratio following on from increase of (horizontal mobile/tablet screens and usage?
