This made history because Apple never copied Microsoft before. https://news.microsoft.com/surfaceduo/

Always loved the Surface Duo. I really liked the separation of the screens too; felt like dual monitors vs. ultrawide. It also forced the technology to focus the valueprop on multitasking versus more immersive/more bigger/more better. I'm curious about the iPhonr Duo; I have not been a huge fan of iPadOS or iOS, the former making me often wish for a macOS experience and the later having felt slower and less responsive over time (mostly due to animation speeds/aesthetic choices rather than a hardware defect).

They made a better version of a Microsoft product, this seems like par for the course.
