Again, I'm really vexed that DJI did not make the differences of bit rate between P3P and P3A apparent when I was trying to decide between the two. I really thought the 4K vs HD and the charger speeds were the only differences. Grrrrr.
Ultimately, I don't think it will matter for me. I am looking at using either Samsung's VR Gear or the Zeiss VR One paired with Litchi to get an immersive headset experience. My current smartphone isn't compatible with either headset, so I will wait until I upgrade to leap on this one. I saw a video (I wish I knew where, I'd provide the hyperlink) where the DJI folks were saying that they were working with Samsung to build a version of DJI Go that will capitalize on the features of the headset. So perhaps I will time my upgrade & Gear VR purchase with the release of the DJI software.
I've read that Litchi's software works with Google cardboard, so I might pick up a cheap cardboard headset to see if I even like this idea. One detractor that jumps out at me is that without immediate access to the touch screen (once your phone is installed in the headset or Google cardboard) you can't switch modes (FPV to Follow, or even Normal to Course Lock). So snapping the phone into the headset means committing to a particular type of flight. I *think* the Samsung Gear VR has cursor control (via head movement? buttons on the side?), but that would have to be incorporated into the aircraft control apps as well in order to work, right?
A future version of Samsung's Gear VR is also supposed to support augmented reality. It would be great if the DJI or Litchi software allowed a user to switch between using the phone's camera (augmented reality mode) for take off and landing and non AR mode for FPV flying. (Always use a spotter if your head is in the goggles, right?)
I always thought that Epson Moverio BT-series headsets held promise, but I think (at last check) they ran older versions of Android making the control software compatibility a problem.
Anyway, I'm always interested in continuing this conversation.
