My biggest concern with this is how easy it would be to steal. If I'm sitting in a train, someone could just yank it off my head and run away. That's $3,500 bucks down the drain. When using a phone for example, I don't really have to worry about it as long as I'm careful. I wear a shirt long enough to cover my pockets making it hard for a thief to lift up the shirt without me noticing and grab the phone in my pocket. When I use the phone, I keep it close to my body. If I were using the Vision Pro, I'd have a giant screen in front of my face. I wouldn't even see the thief coming. Maybe they could make a strap that you attach around your chin like a helmet and charge $1,000 bucks for it. Or perhaps screws to drill it into your skull.
