I have a Quest 3 - Apple has media/productivity tasks in the bag with Vision Pro. Just watching a youtube video on the Q3 is such a hassle - first, you can't use the YouTube app unless you want 480P. Then you open the browser, go to youtube, find a video, tap play, then try to tap the full screen button but you will miss 75% of the time and instead hit the playback bar to scroll to the end of the video. So then you hit the start of the playback bar a few times as it usually doesn't actually work. Then you get it into fullscreen finally, but need to reposition the window because the fullscreen view is huge and usually gets sunken into the wall in front of you. But you can't move it with your hands (Because...they just didn't implement it?), so now find a controller to move it into position. Now 10 minutes later, you can play your 2 minute youtube video.
Oh yeah - and if it is side by side 3d, then you have to change into that mode. And the playback controls are rendered normally, so if you are "hovering" over the video you are going to get some uncomfortable depth perception issues because the video is 3d, but the controls are 2d overlaid on top of that.
A lot of these issues are just because hand tracking is still "beta", but I think in reality the problem is Meta started out as a VR, controller only headset designed for gaming and now are trying to quickly transition to being an MR, hand controlled system designed for productivity.
I've watched the iPhone SBS videos...but so far they haven't been great. I don't think the iPhone recording is the problem though.
