1. Its a different take on the problem, stitching multiple lens and sensor data to make a whole that's better than the parts. Even if this don't work I think that idea would probably live to see another day.
2. There are comments about DSLR being fast, viewfinder easier to work on all situations and I agree to all of that. But I think the biggest point is what one of the founder said in the video, it doesn't matter if you have the best camera @home. This is something you can carry just like your smartphone.
3. Yet even this is a separate device, what I would like eventually is for this idea to be improved and implemented for smartphones. Maybe a 3 lens system that's not as good but much better than current cameras?
4. And I really loved the way the lenses were placed horizontally. That looks to be a simple yet effective innovation (not that I know if it has bad optical consequence).
