I love my M1 iPad Pro. Being able to hold the web in your hands at tablet size is great. It has completely changed my workflow as a semi-pro photographer: Lightroom and Affinity are amazingly performant, and this iPad has Thunderbolt
I/O. Lumafusion for video is also incredible, and I can't wait to get my hands on DaVinci Resolve.
The biggest thing I miss, and it's a dealbreaker for a lot of my work, is the lack of a shell. I would be over the moon if they released Terminal.app for iPad, even if just in a persistent sandbox environment with no real access to the system. I just want to be able to manipulate local files with that toolbox. Obviously, full homebrew support would be key.
There is just still no "app" that can (ever, probably) replace the utility of a shell.
