>Or feature Thunderbolt rather than normie USB-C so you can record 4/8K ProRes to an SSD,

My iphone 16 pro max can do 4K ProRes HDR or Log at 120 FPS when plugged into a SSD. If I had more builtin storage I could do it without the SSD. If you don't mind more dongling you can also have an external display along with the external SSD.
