To be fair I think any major product in Apple official website should have around 5 years support from the day that customer can order. Most of the customers are not into tech and they would not even know it only has 3 years support until they don’t get the update.
That’s not how anything works. That iPad came out in September of 2021, so its almost a 2 year old iPad, and already 2 years old the day you buy it. If you buy a 2021 year model vehicle, is it new if you buy it new in 2023? No, it’s a 2 year old vehicle (But new to you).
This is why if I buy electronics within a few months they are released. If I can’t afford it at that time, I save up for the next release. I bought an iPad Pro 2nd generation that came out in September of 2017 in December of 2017 and it’s still getting support today (until iPadOS 17 comes out). I got it because I got a great deal on it with my trade in, and my old iPad was giving me issues. That’s getting 6 years of support, so I felt I got my monies worth. It will probably get a few security updates here and there, but I’m not counting on it.
Wait until Prime Day, maybe you can get a good deal on the iPad 10.
