Mine's going back. I really do appreciate that this form factor exists, but I'm honestly surprised Apple's let the mini ship with iPadOS in this state. By default, Safari requests desktop sites, and at (again, default) 100% page scaling, everything is absurdly small. I've spent a good bit of time futzing around with text scaling, Safari settings, and text sizing in apps that have their own setting, but the experience is just really inconsistent and wonky. Widgets are tiny.
I'm sure a lot of people appreciate the density, but I can't get it to work for me. My eyes are in pretty good shape, but just look at the size of the time/date text in the top left. Yikes.
