I really like that they're not marketing this as a VR headset for gaming, but rather as a computing device. This is essentially a replacement for an infinitely gigantic monitor. You can pretty much have the experience of watching an IMAX movie, which you'd never even get close to no matter how huge of a home cinema projector you buy. Though, of course, for 1 audience member only... Still, it's an experience that was not at all even remotely possible from home until now. And they solved the most annoying problem with VR headsets: that they isolate you from the world and render you blind, tripping over your furniture. No silly controllers, just your eyes and hands, this is what Apple has always been good at.
I guess this is the first non-entertainment use of a VR headset, and it's going to be pretty interesting to see what it will feel like. You could get some incredibly complex tasks set up for video editing and multitasking. Always seeing your environment while using it is a great idea, there's no need to always be isolated from reality. In fact, I guess full immersion is something you'd only want in specific cases.
This seems to be more like the iPhone or the Mac in itself: it's meant to do anything and everything that a computer can do, rather than just to run games or some other specific use case.
There are some features that feel like gimmicks, like taking photos with it or casually reliving memories from your iCloud library... But it seems to have every possible feature you can think of so it could literally do anything you want. It's like an "experience" interface for whatever it is you'd want to do on a computer, rather than a device just for gaming or just for specific types of content, which would have been greatly limiting (especially on Macs where gaming is more and more non-existent).
Of course it's still a year away and even then it will only be available in the US, and even then it will cost an arm and a leg, and God help you if you need glasses because I'm sure those Zeiss inserts are going to cost your other arm and your other leg. And so will the external battery and who knows what else. But it does seem like it's aimed at "Pros" from the name, which would imply that it's not so much a personal consumer device, more of a productivity/corporate tool, in which case you'll buy it anyway if it makes your work more efficient and helps you make more money.
But it seems like if you'd only get this for fun and entertainment, then you might not get the most out of it for its price, because I bet you can't even use it on your PC to play VR games. So if you want entertainment/gaming from VR, then you'd be much better off with a PC and a VR headset.
