You’re less than 3 years into your current iPad Pro, you seem to have no complaints about its storage capacity or RAM limitations now (though we all can admit that upgrading to a 2021 will give you improvements over your 2018 related to RAM regardless of which you choose) and yet the next latest and greatest is here causing a purchase consideration. No judgement here, there are many of us who are excited about these new machines, but I agree with the sentiment that if you don’t need one right now just wait for the software to develop that takes advantage of the hardware differentiation. Certain apps will surely benefit from the additional RAM and if there are any on your radar then thats where you could focus your attention on to monitor their performance improvements in order to inform your purchase decision.
As for using an iPad as a main storage device to each his own but I wouldn’t; I just went through a pain in the arse situation with my wife’s Air 4 which decided not to recognize her passcode, forcing a complete wipe. She hadn’t changed her passcode recently, is the only one with physical access to the ipad, and multiple attempts to use the correct passcode were in vain. About the only thing I could think of is perhaps something had happened during auto update to 14.5. In any case it was no big deal for us since our family is on a large iCloud storage plan but the lesson was to expect the unexpected.
