I think the Spark will be around for a long time despite what people are saying about the Mavic Air killing the Spark. It's half the price of a MA and why would DJI just release the Portable Charging Station just before Christmas if they were planning on discontinuing the Spark. The Mavic Air folds up smaller but the Spark is still more portable especially with the charging station and bag. I love my Spark! I have had it since Christmas and it is a complement to my Phantom 3 Standard. I can just throw the Spark, Charging Station, controller and 2 extra
batteries inside the Charging station bag and go hiking, skiing, snowmobiling, etc for a whole day and have the ability to re-charge the drone plus 2
batteries and my iPhone without ever having to come back and 'plug-in'. No other drone in DJI's lineup can currently do that including the new Mavic Air.
