To all those who've been raging about this for the last week, and especially those who have written voluminous comments here (and elsewhere), consider this: is this really worth your time?
How much time (in hours) have you spent on this "controversy"? Multiply that by whatever your hourly rate (in your business or on your job). Now, take this monetary amount and extrapolate out to late September, which is when iOS 16 will be available. How many more hours NOT spent kvetching, but generating income would it take to accumulate the amount you need (minus the resale value of your current device) for either a new M2 iPad Pro, or an Apple Certified Refurbished M1 iPad (which will be available by then). You'd have 90 days to do so.
Now you have a choice. You can 1. positively focus you mind on productive activities that will get a great new iPad that runs Stage Manager, as well as includes other M1 (or M2) enhancements, or 2. continue in the victim mindset and defiantly hold tight to your aging iPad in order to prevent Evil Apple from greedily extracting more money from you. Because, after all, Apple's talk about customer experience is utter ******** and their true business motive is to oppress and gouge.
