A Mac from 10 years can do everything that a Mac Pro can today. Ironically, the only difference for today's M1 Macs is that Apple is transitioning the OS to the silicon introduced in the iPad. (Remember: The Mac with Apple silicon developer kit was a Mac mini running on a A12Z processor!)All of that can be done with older iPads as well. Apple, give us a more advanced iPadOS to utilize that M1.
Apple is putting better hardware in iPads for iPad apps to run faster and perform better. There are many more professional apps and utilities on iPad and iOS than for MacOS. My firm develops several custom B2B apps.
So what are the more advanced features you would like in iPadOS, other than run MacOS?
