Keep your eyes on Craigs List and Ebay for NEW or ALMOST new iPad
Mini 4's.
I just got a BRAND NEW iPad Mini 4 (16GB - WIFI only) on Ebay for $319. It was still in the shrink-wrapped original Apple box and works beautifully. The display blows away my Galaxy S7, and is much better than the iPad
Mini 2 or 3. It has a better, more "glare resistant" screen, a better, brighter display, and runs MUCH faster than the iPad
Mini 2 or 3. The (American) seller I bought from had a 99.4% approval rating. He paid shipping (insured it) and I had it in 3 days.
Watch some YouTube comparison videos about the iPad
Mini 4 VS. earlier versions.... big difference.
I was afraid I might miss the GPS function but I don't at all. It just takes a minute before I leave my house to get online with it and cache all the maps that I might need, and then I'll have them forever for that flight location.
The only functionality that I give up is the "Follow Me" function. I've never used Follow Me before, but if I need to do that, I'll just use my phone. Logically, if you're going to have your mavic follow you, you probably will be doing something that will require your hand(s) free anyway, and you'll just have your controller in your pocket - harder to do with a tablet attached. And I cannot reset the home point to my new current location with the iPad if I'm moving around, but if I need to be moving and flying at the same time, I'll use my phone.
* At the rate technology changes, and the rate that they update the DJI GO app, it is ridiculous, IMO, to spend good money on outdated or ALMOST outdated hardware, like the iPad
Mini 2, when the newest version is only about $100 more. I've heard they may be coming out with a new iPad Mini this year, making the iPad
Mini 2 three generations old already. I wonder how many more new versions of DJI GO will be released before the iPad
Mini 2 isn't even powerful enough to run it? It is a VERY resource intensive APP. Plus, with the iPad
Mini 4, hopefully it will still be new enough to fly the
Mavic 2.0 when it comes out someday.
I made this "older-technology-saves-money" mistake just a few years ago, when I got a great deal on a new full-size iPad 4th generation, which is now already too outdated to even INSTALL the DJI GO and many other new applications.
You've got a state-of-the-art drone ; arguably one of the best drones money can buy for your needs.
Why diminish the experience by saving $100-$150 on a cheaper, older, slower, sub-par display?
Just my 2 cents.
