Few things to note on why this will be a success:
Intuitive - If you compare to the current products on the market, they make you feel alien. You have to not only wear googles, but have the hand controllers. Wonky UI/UX - It's simply not a human experience. Apple waited this long to get the FEELING right. You put on these googles to take you into a new world, a new enhanced world where you do everything you naturally would do to control it. Speak, hand gestures, eye movements.
Ecosystem - This is always the difference been using an apple device period. It fits into the life that is designed for you. Not how do you fit this into your life. People still don't get this being the biggest differentiator and Apple's reason for success?
Immersive Content - They glossed over the 3D camera and how you can truly capture a moment. Think of this tool applied to a creative industry... but really PORN. Let's be real, porn dictates the path of technology. Blu Ray vs HD DVDs, HTML 5, Death if FLASH, all things that have been decided by the porn industry. Wait till they get their hands on this haha
You gotta know the future will most likely going to be like READY PLAYER ONE in a lot of ways, hopefully not the negative, but think of the positive bits like education. Once these become cheap to donate to schools across America like they did with the Macintosh, education will finally be reimagined.
As always the first generation are for early adopters, people who see the future and cant wait to play with this. They simply seed the way for mass adoption. Just like the iPhone and iPad Vision pro will change the world.
$3500 for insane state of the art sensors, lcd screen, camera, spatial audio, slick design, I mean people are crazy to think tech is cheap and easy to invent, design, iterate, then bring to market.
