Better stabilization & zooming would be hugely useful to almost any mobile photographer, though I’m more intrigued by possibilities of better depth sensing & segmentation:
PetaPixel writes,
Instead of the mechanical optical zoom found in traditional zoom systems, Corephotonics’ technology zooms using just the two cameras and no moving parts. One of the cameras has a telephoto lens and the other has a wide angle one. By combining the images from the two cameras together, Corephotonics is able to achieve both optical zoom and better image quality.
