As an owner of an M1 iPad Pro 11 - I’ve been thinking the same thing. I know I can just drag my MacBook around if I really need a keyboard/mouse - and the iPad Pro 11 is not easy to read on without support (I use a body pillow). The idea of having a kindle size like device to read books again would be nice. But I’m afraid I’d miss the screen of the 11. The fact that no store here has had them available and the high price of the mini has kept me from entertaining the mini. The refurbished 5 has been tempting (To go for a pure book reader).I had this same debate over the last couple of weeks. I don't like using iPad Pro as my main driver anymore, but still love iPads and was missing my trusty Apple Pencil. The iPad mini 6 was the iPad mini I had been waiting for YEARS for, so I was ecstatic to see them finally do it, but didn't bother buying one because I had just gotten rid of my 12.9" Pro and already had a 13 Pro Max.
So then, I started wondering--wouldn't an Air or 11" Pro be the better buy? And I almost went that direction, but I really just want the iPad to be my portable book/notebook/magazine. It's my "tablet" in the truest sense of the word. I almost wonder, now that the forehead and chin are gone and it's really more like an iPad Pro mini without some of the bells and whistles. And it has the latest A chip in it, unlike the Air.
I think the new mini is exactly what I need an iPad to be at this point in time: the not-iPhone not-Mac that I can grab and go and do some really specific things with. It's not much bigger than my 13 Pro Max, but that's not really the point. It's a completely different kind of device with much more comfortable aspect ratio for games and movies.
Did you end up getting a mini?
