I decided that I am going to return my M1 iPad. Sure, the screen is beautiful, but I was hoping for more new capabilities that would make the M1 experiences potentially materially different from that of my 2018 iPad Pro.
I have really enjoyed CenterStage, which is super cool and genuinely useful. I have also enjoyed the improved screen, but as it stands I'm not getting massive day-to-day improvements in doing my work.
I will be prepared to re-purchase the device if and when there is justification to do so -- and they seem to be in stock at my local Apple Stores. But from what I can tell, everything coming in iOS 15 will also come to my device. I'm sure with time, my beloved 2018 will finally start to feel old. But I'll put the $2k back in my account for now. I'm sure I'll be back in due course, though...
By the way, I may be disappointed that there isn't more good stuff here. But it's my choice to buy the device or not, so not throwing shade on anyone -- Apple or otherwise. Happy to have the right to return it -- sorry for those outside the window though if they too wanted to return.
