Apple has announced its long-awaited mixed reality headset at this year's World Wide Developers Conference. The headset, which is essentially a lightweight and specialized Mac that you strap to your face, represents Apple’s entry into the world of virtual and augmented reality, which, despite much potential, has remained a niche market dominated by gamers. Apple hopes to bring that world mainstream the same way that they made personal computers mainstream with the Mac, and smartphones with the introduction of the iPhone. Whether they will succeed remains to be seen, since the device will not reach audiences until 2024, and even then comes at a steep retail price of $3,499 that puts it out of reach of most. Nevertheless, the Vision Pro represents Apple’s first new product type since the launch of the Apple Watch in 2015, and many expect it could, like the iPhone and the Mac, change the world.
