Ooo, clean renders!
If we're here for suggestions, I want two more Thunderbolt ports in the top- and bottom-left corners on current models akin to where old school headphone jacks used to be on vintage (technically obsolete but whatever) iPhones and iPads. In landscape these fall at the lower-left and -right corners expanding and streamlining high-performance peripheral connection on either side. iPad Pro has M4, so do MacBook Air and Mac mini, give iPad Pro more Thunderbolt; likewise, MacBook Air supports its own and two external displays, lets do more with iPad Pro! This is also clean if you have a folio case and your iPad positioned laying down where the ports at the top.
A software suggestion would then be able to run full macOS environments on up to two 6k Thunderbolt Displays on iPad Pro with M-series Silicon. Full external display windowing needs a keyboard and cursor anyways, just appropriate Universal Control having the cursor change when spanning displays, unify the file system and task manager, and implement window placement restrictions for incompatible macOS programs. The originally placed Thunderbolt Port can connect to a dock, iDon't Kno. Then normal iPads can become stronger with normal iPadOS external monitor windowing improving their value.
If it was something bigger, maybe edge-to-edge OLED with a hidden Dynamic Island and the OS will border like current iPad design for palm rejection and I guess literal handholding. Then when docked or used with a keyboard and cursor, the elements will shrink a bit and the border will illuminate expanding the screen and Dynamic Island will appear similar to Mac notches.
