Not sure why you need a wonky LiDAR Scanner on the one camera nobody uses either but here we are
I'm far more interested in the LiDAR camera since I do 3D printing and whatnot. If it could build a reasonably accurate 3D model by scanning an object that I could touch up a bit and print, it would be awesome. But that's really the only thing I care about it for right now. I think the real benefit of the LiDAR is when Augmented Reality really starts to become a thing that people use more frequently. It's still a little ways off yet, but that will help place things more accurately in the world, and a small LiDAR sensor like that could be a huge benefit to self driving cars as well.
The U1 chip, I think is nice, but I don't really care about Tags either, and I rarely air drop anything so it's benefit is very limited to me. So I really don't care about the U1 chip. I do just fine keeping track of my stuff as-is today.
Granted this is just my personal opinion on it. I can see how many people would care more about U1 today than LiDAR, but I'm the other way around.
