I'm a big fan of the mini form factor, so I ordered the iPad mini 6 right away when it released back in 2021. Unfortunately, it was such a let down that it's mostly been laying in a drawer over the last couple of years. Had I not had the iPad Pro, things might have been different, but the jelly scrolling definitely ruined the experience for me.
I've offered it to my girlfriend, but she thinks the screen is too small and not enjoyable.
I'm still glad they make it, but I think it should be positioned below the 10.9" base iPad.
