Agreed. The AVP works so well as an external monitor. I use it a lot while traveling but I’ve found myself preferring it even at home.
Comfort during long sessions can be a challenge. While I’m fine with Apple’s dual strap, my current setup is an Anapro forehead strap and no light shield. It does leave an unsightly mark on your forehead but I find it very comfortable and I like letting my face breathe.
