There is no way of getting around how bad those top and bottom bezels with the off-center Home Button look, especially when you compare it to the iPad Air.
I prefer function over form any day. I could not care less what the bezels look like as they make the mini much easier to hold and manipulate in landscape mode than most modern tablets that have tiny bezels. I still use my iPad mini 2 for reading, and if it wasn't so old and getting slow I would use it for all other iPad functions too. I like the form and I like the feel and portability. As long as the mini 5 has enough power and the updated P3 screen I will be very happy. But to each their own, of course...
