I still find my iPad Mini 3 to be perfect for my needs, but I am SO glad to hear they are finally making another Mini! I much prefer the smaller devices - had a full-sized iPad back in the day and couldn't understand why anyone would gravitate to a smaller screen...but I have never looked back since I got mine. Much more pleasant to hold while "couch surfing" and easier to store or tote around. I honestly don't "see" the screen as small. When I am engrossed, it is just fine for what I need it for.
Glad to know that if I needed to replace mine, there is now going to be a new "upgrade" option out there. And hey, I hear they didn't get rid of the headphone jack on this one..!
