iPad Pros are priced at the point where users should be able to expect a Pro experience. To me this means functionality above and beyond what I can get with another tablet, not just some artificial delineation of usual features like screen quality or the quantity / quality of speakers.
What I, personally want to see is better multitasking, better support for docking to external peripherals and using the iPad as a standalone computing device, and a better filesystem.
Apple did a few things to get them in the right direction - the windowed mode, or even something as small as getting rid of the stupid round mouse cursor.
But they also introduced some other changes that actually made iPad harder to use (the way Preview interferes with Files workflow, for example).
I don't expect the iPad to be a direct Mac replacement, but I do thing that a "pro" model that costs as much or more as a Mac should be a functional replacement.
My M1 Pro is likely the last Pro iPad I am going to buy, unless there are some additional functionality improvements. I would do just as fine width an Air or even a base model, if I still have to keep a separate laptop.
Hopefully with RAM and SSD shortage because of the demand for AI workstations this will single web developers to start making websites that are less bloated. I remember in 2010 when people only had 2 to 4 GB of RAM. Websites and browsers where less bloated on system resources.
