Honestly, you can get the fit super comfortable if the person at the Apple store you have is very chill with you trying out 10+ fits (I did 9 fits). But they were so slammed that they included the wrong sized head-straps, so I ended up being super uncomfortable when I set it up at home.
I don't think it's heavy, but you will feel it if you have it on for more than 1 hour. I don't get any wobbliness from the headset, which I would get on my Quest 3.
The FOV is really god awful on it, to the point that I put on my Quest 3 after the AVP and it was just miles ahead for comfort. The green edging reminds me of the Samsung Gear VR or wearing glasses.
And the app offerings Day 1 just aren't there.
The only good thing about this headset is Cinema (for Apple TV only), Environments, and eye tracking which is gobsmackingly good but I would much prefer if they showed a clean line to where my eyes were pointing like the Quest controller does.
The demo is really magical in the store when you have your mind blown by the eye tracking, but remember they don't show you the keyboard or the awful web browsing experiences for a reason.
