I've jumped back onto the iPad train so many times and i find myself not using the device for extended periods of time, and then it just becomes an insanely overpowered media consumption device.
I bought into the magic keyboard and tried to convert my daily workflow to the iPad but i found that it was an exercise in frustration. Aside from the magic keyboard attachment being woeful to use on your lap, the overall OS just doesn't feel mature and competent enough to use in my use case, though i know many who do their whole jobs on an iPad.
Multitasking and app switching needs an overhaul. They're holdover from the iOS era and they don't function adequately enough to be considered true multitasking in comparison to fully fledged OS' like macOS and Windows. Static thumbnails of applications, not being able to pin apps, switching back and forth to read information, running into apps that don't support split screen, and the overall "zoomed in" oversized nature of the UI just makes iPad OS a chore to use -- not mentioning the fact that most apps on iPad OS are gimped in comparison to their desktop counterparts, such as Photoshop and Microsoft Office suite.
A friend of mine is a realestate agent who does their entire job on their iPad pro from signing documents, taking photos, writing up agreements, taking signatures from tenants, even down to using the LIDAR scanner to do floor plans, and much more. I'm envious of those people, i wish i could make the iPad work for me.
When Apple announced the M1 iPad pro i was kinda shocked because the iPad Pro was already insanely fast, to the extent that i'd call it over engineered/overpowered. The OS is no doubt holding the hardware back and i honestly can't understand why anyone would drop that much money on something like a 2TB iPad Pro, aside from content creators who have found a workflow that suits their needs (i.e., tethering their camera to their iPad and editing photos on the fly in Lightroom and posting directly to their website/social media).
Nothing short of a full OS overhaul, or macOS native on the iPad would convince me to go back at this point.
