I have an iPad mini 4. I take it almost everywhere. It goes in to the kitchen for cooking, the bathroom so I can listen to my favorite podcasts or watching my favorite shows during my morning routine, in the living room for browsing while watching TV, in the bedroom for reading before bed, in my car for directions, in meetings for notes. It's a very versatile machine. Part of what makes it so versatile is it's size. I bought it because I needed something bigger than a phone, but smaller than my 13" Macbook. I don't take my macbook into the kitchen because of it's footprint. I don't take it into the bathroom because there's nowhere to put it. I don't take it to meetings because it's an unwelcome barrier between me and my clients, I don't watch TV on it or any of the other things I could do with my iPad. That being said. The footprint and power of the 12.9" IPP make it a laptop replacement, but not an iPad replacement. I feel like I'd still need a device with a more manageable footprint, that could go everywhere, was less...unwieldy, and pocketable/purse-able for all the on-the-go tasks I mentioned earlier. So I'm thinking that it's not a catch all machine. Smaller iPads are companions to desktops/laptops, but the 12.9" IPP needs it's own companion. It needs at least an iPhone, but more likely on of the smaller iPads for the things it's too big to do. A few disclosures: 1) My husband has a 12.9" IPP. I use it more than he does, but not the way I use my mini which is sort of how I came up with this idea. 2) I purchased and returned the 9.7 Pro because the mini fits me better (and again..I use my husband's pro if I want a bigger screen) 3) I'm a strange apple fan. My ideal setup is LTE Mini with a stand alone LTE Apple Watch. I'd love to cut out my iPhone entirely.
