While I agree I do some photo panoramas and other editing that chokes up my 6GB 2018 iPP. I'm waiting for an 11" mini-LED or OLED model but I will appreciate the speed/RAM upgrade of the M-class models even with the current software. The iPad Pros really aren't for everyone! If the Air were to get ProMotion and HDR (which I suspect will happen soon if not tomorrow) the Pros will become even more niche as the only buyers will be people who want to run specifics apps and workflows.I wonder if paradoxically people hold on to their iPads longer because of the limited software. Whereas, if the software was taking advantage of the hardware year to year, there wold be more emphasis on upgrading sooner and Apple would be making even more money off iPad sales. As it sits, anyone with a 2018/2020/2021 iPad Pro has no real reason to upgrade unless iPadOS has some bigger changes.
That's honestly the case with Apple's current "pro" desktops and laptops and I'm OK with that. I think it makes more sense.
