I tried the simple route of being nice and the only response I ever got was "You just don't understand! I need Stage Manager because I wanted an iPad but I also just plug it into a monitor. I know I could have bought a Mac mini, Mac Studio, MacBook Air, or MacBook Pro, but I am difficult and complicated and that makes me unique. I apparently can't handle a basic Bitmap iPad Home Screen and need something extremely over engineered and complicated that resembles the laptop I should have bought but isn't as good, has a bad filing app that should probably be worked on, and can't do any Pro apps like the laptop I probably should have just bought in the first place and costs the same amount of money at this point but I like to be complicated, difficult, and obnoxious and go against what is effectively the more logical choice."
But no, please focus on the annoyance and frustration of having to wait for years for Apple to bring Pro apps to the iPad and fixing iCloud Drive but having to wait for them to first bring THE WEATHER APP we sorely needed and a CALCULATOR that apparently some people are too lazy to find in the App Store.
I have had to wait since the iPad Pro 10.5 that Brought Files app to the world for a better iCloud Drive experience where my 2 GB video file I watched on my iPad last night has now decided to auto-download to my MacBook Pro without my consent. But no, that can't be fixed right now. A small slice of very loud, annoying and vocal iPad users who obviously bought a tablet by mistake and not a laptop demanded a 1980s Desktop UX on a tablet. So, we get Stage Manager, which sucks and doesn't solve the multitasking issue on the iPad but shuts up and distracts the very vocal people who mistakenly bought a tablet.
So, now, Apple will just take their middling criticisms and SLIGHTLY update Stage Manager every year to keep them distracted and focused away from their poor product choice decisions so that Apple can focus on more important things like iCloud Drive users fleeing to OneDrive, Pro Users becoming fed up with NOT A SINGLE Pro app on a product labeled Pro, and a Silicon strategy that will essentially bankrupt Intel and strangle Android chipmakers struggling to push out more performance per watt despite Android having a never ending problem with memory management.
Pro Users are twiddling our thumbs wondering when I won't have to lug around a MacBook Pro anymore for on the go editing in Final Cut/Premiere/etc. We wait patiently for years as people who OBVIOUSLY want a laptop buy a tablet and demand laptop features on a tablet WHEN THEY COULD HAVE BOUGHT A LAPTOP.
It's like some people wanted tea, but bought coffee and demanded the coffee makers engineer coffee to taste more like tea, when they could have just BOUGHT TEA.
