At last Douglas Adams vision of panic sensitive sunglasses can truly be with us.

More seriously, with a 4k panel for each eye this might finally be something that can create a reasonably immersive experience.

No doubt, there is a tonne of processing power and capability under the hood, but 2 hours?  That really isn't great.  The size of battery pack suggests roughly 5,000~6,000mAh @ 3.7V - about 15Wh say - so the product is pulling about 7-8 watts in normal usage.

Compared to what an iPad pulls when playing a movie, around 2-3 watts?  (30Wh battery with 10hr runtime.)  It's quite a big penalty for augmented/virtual reality, and is going to hamper adoption as an 'all day' usage device (they suggest it for spatial computing, so would people be expecting to use this for a whole workday?)

Yeah.  2 hours is not long.  Maybe that matches how comfortable it would be to wear for long periods of time as well.  I guess you could plug it into a USB C adapter if you're just sitting somewhere but that's pretty un-Apple like.  As others have said, this is clearly gen 1.

Still kinda amazing from a technical perspective that all processing and display it is doing is being done with only 7-8 watts of energy.

One app I'd like, as a EE, would be instrument displays (scope, DMM, etc) as I looked at, and probed, my DUT.  Imagine a floating set of waveforms just above the gadget you're debugging.  And maybe with voice + eye tracking control so you don't have to move your hands to change settings.

An iPad doesn't need any processing at all to display a static PDF, this thing...
It needs to run:
- two 4k displays (estimated 3840x3000 per eye)
- 3D rendering of everything
- inertial motion tracking
- 12 camera's
- room detection (probably some photogrammetry)
- gesture detection (lidar, liek face-id)
- the puny app you run

I'd compare that to an macbook running games: https://youtu.be/jYSMfRKsmOU?t=50
Then 2 hours is pretty good if you ask me.

Schematic realtime augmented onto the pcb...  :-/O

I'm sure Apple have tried to optimise battery life, and of course there's a lot of hardware to run, but the problem is: the user might acknowledge plugging in a charger to play on their MacBook, but will they be happy to have a charger for their VR headset always tethered?

I guess we will see. IMO they need to figure out a way to get 10hr+ runtime in normal usage to be mainstream successful, then you have a full day's usage before needing to charge.
