Just want to chime in on what I think are some wrong presumptions. You’re right, I wouldn’t wear it outside, but I would use it in various places around the house (mostly on my couch for work or play), in my office (for work), and in a hotel or guest room (work or play). In these places it would be great to have large resizable floating screens, and in those places an iPhone and my Mac setup at my desk won’t help me. And I don’t foresee sweat will be a problem if the room I’m in is temperature controlled (pretty much always) and assuming I take as many breaks as I do when using all my other devices, which is at least every two hours. As far as battery, since I would use it mostly stationary I would mostly keep it plugged in. I only foresee needing battery when going to the kitchen to grab a drink or wanting to watch a video while doing chores around the house (assuming VP can do that).What I am saying's that nobody normal is gonna wear this thing outside. So, it would be limited to your home so then why would anyone pay this price to have the same thing they have on the Mac and iPhone and sweat in it while having to swap batteries every 1-2 hours. This will go the way of 3D TVs and curved TVs - unless they can substantially and I mean substantially shrink it to fit regular sunglasses which will happen in approximately 30 years. And even then the commands will be very weird as today Siri can't even understand simple one word commands. Every product so far made sense: iPad/tablet - watch movies in bed, read books, draw almost better than on paper, browse web in bed, take it on an airplane, vacation, etc. Watch, tells time, looks great, it is very comfortable, tracks exercises, answer calls, leave iPhone at home, etc, etc. Vision Pro - nothing - nada- zip -zilch.
I don’t know if the VP will be a “success” however one defines that, but I do know it’s very easy to look back at well-established products and list their qualities.
