I am in the same boat as ratephi. I just recently parted company with my Phantom Pro 3 so I could move up to an Inspire. Just waiting for the rest of the funds to order an Inspire. Anyway, I learned a lot with the Phantom 3. Talk about a greenhorn, I attempted to use a Kindle Fire with the Pro 3. I liked the size and the $50 price. Duh! I now use the Fire to hold down some papers on my desk. Next up I tried a Samsung Galaxy T4. It worked but lag and stutters left a lot to be desired. I had an older mini iPad, and while it performed better, there was still lag and stuttering. Around this time I found this website (Inspire Pilots) and quickly found a ton of mistakes I was making. First was not reading the instruction sheet that came with the Phantom more closely. Maybe I would have seen the list of approved devices . Anyway after reviewing everything I have read on these pages I have narrowed my choices down to the Mini 4 and the Air 2. My personal preference is a 64 gig WiFi only Mini 4. I just like the size better. The $100 cheaper is not a major issue, but still that could be used toward adding an additional battery. I will make my purchase at Best Buy since I can try it and return it IF it doesn't measure up to my expectations. I hope the Mini works, I don't like returning stuff and having it end up on the open box table due to my ignorance being at fault. That just drives prices up. Anyway, I want to thank one and all for your input and for helping me make a better, educated decision when I walk through Best Buy's doors again. I intend to post my results here, good, bad, indifferent in hopes of helping someone else down the road make the correct choice when there time comes. Thanks again to everyone for your input!
