What is the difference between this and a cheap gimbal and a GoPro Hero 4? About the same price... OSMO is more visibly attractive, but the HERO 4 is a mature product and you can remove the HERO 4 from the gimbal and use it in other applications. I dont see the reason that this product is getting so much play. Now if they released the MFT version at this price, I could completely understand the excitement over that.
