I ended up doing that as well.
I really like the mini overall, I swapped from an iPad Pro 12.9 M1 2TB to the Mini A17 Pro 512GB because I just wanted a smaller tablet mainly and the larger iPad just wasn't getting much use lately. The last time I had a Mini was when the iPad Mini 3 came out, so it's been a very long time. I love the smaller size and compared to the larger one, and it pretty much weighs nothing in comparison, so it's much more comfortable to hold.
I really do miss the better quality screen, dropping from 120hz to 60hz is extremely noticeable to me, literally a night and day difference and I really miss Face ID, I haven't used Touch ID in many years, not since the iPhone X came out so it's really annoying to go back to that again. Why the hell have they not added Face ID to it by now is a really a mystery.
The Apple Pencil compatibility annoyed me as I had to spend £129 just to replace a perfectly working pencil, so that's money down the drain for no reason and I though Apple wanted to be environmentally friendly, guess not. Will say though that the new features on Pro one are pretty cool, but it would have been nice to use my previous one, ended up making the squeeze gesture a shortcut back to the home screen, and it works great. I just wish Apple made a Mini Pro that has all the features of the larger tablet but sticks to using the best iPhone chip at the time if they can't make an M CPU work due to power usage and heat, I bet that thing would sell amazingly well.
Overall though I'm extremely happy with the iPad Mini 7 as it's lightweight, still fast as it's pretty damn close to the M1 CPU and far more portable, screen quality is OK, nowhere near the mini LED or OLED, but it's fine. I'll definitely be using this one more.
