Well there's no denying that's inconvenient even if it's what you prefer.
But why? I use a Leobog Hi75 on my PC which is a very thocky mech board, but I still appreciate the MacBook keyboard for being a decently satisfying keyboard especially considering how thin it is.
If I were using the Mini, it would be because of the pencil. And if they gave iPhones (especially Pro Max) Apple Pencil support, although the experience would be a bit better on an iPad Mini, would it really be worth it for most people to buy, charge, and bring an extra device everywhere?
But, because Apple won't do that, it's a good device for some people. 120hz would make it great.
