This is one of the more thoughtful posts. I'm an AVP owner, and a happy one, at that...but I'm happy just using it for 20 minutes a day for unique viewing experiences. Panorama photos, 360 content, 180ºVR...those are really cool. Like, really, really, really cool. I FEEL the content I'm looking at.
However, I find the lack of compatibility with YouTube and several common 3D and 360 codecs frustrating. I've followed some content creators that have helped get around some of it...but damn, it really seems like AVP was released six months early...the whole cart before the horse phenomenon. Perhaps that was by design, but I feel like I got access to a developer tool, and I'm not a developer.
I'm expecting some major announcements at WWDC. Execution used to be Apple's strength. This can't be the plan. There should be a major integration with Final Cut Pro and a distribution network (whether that's YouTube or someone else) to help gain some momentum.
BTW...one other thing. High quality, immersive-content file sizes are HUGE...I had forgotten what buffering was, but now I've come to expect it every time I want to see something.
