I agree with Buzzy and MDKEY, you're better off taking advantage of the lower cost of the original Mavic which is likely to drop even further with the Platinum on the horizon. Don't be a sucker like me though, skip the "fly more" bundle as the bag is too small, buy a couple spare batteries and a hard case and when the Platinum comes out grab a set of the more efficient props.
Also, if like many others you start with a phone as the screen then upgrade to a larger tablet, don't waste your money on Amazon/eBay mount adapters, go straight for the Mavmount v2. As for devices I'm extremely happy with my Asus Zenpad 10.1" tablet but IOS devices generally have less compatibility issues with DJI GO 4.
Good luck and enjoy your new Mavic!
