The mini is the absolute sweet spot for me - enough portability that I don’t mind the many restrictions of iPad OS. But the A-line chips and low-quality screen are problems, and not being able to properly dock it at a monitor is a real hinderance. None of those are addressed here, unfortunately.
Speaking of screens, I wonder if they fixed the jelly scroll. It doesn’t bother me that much on my mini, but it would be ridiculous to keep that flaw as-is in the newer gen.
I'm guessing Apple is using an IPS panel meant for landscape orientation (i.e. the image scans from the top/bottom) in a device mostly used in portrait orientation. This causes rolling shutter distortion when scrolling contents.
