Re: How does the Hololens 2 matter?
#2> Hololens 2 now has a 52° diagonal FOV and a 3:2 aspect ratio - so 43° horizontally and 29° vertically. [...] but it IS more than 4x the area (525°² vs 2236°²)
It looks like the author got confused and multiplied the wrong numbers. 43 x 29 = 1247, so this is about a 2.4x increase in area.

#3"The field of view (FoV) is the extent of the observable world that is seen at any given moment."
FOV is better characterized by a 2-dimensional measurement, like square degrees, or steradians, than a single 1-dimensional measurement, like diagonal angle. "2x improvement" sounds like a perfectly valid way to describe a 2.4x increase in FOV area to me.

#4The UI for Hololens 1 was terrible. Having to hold your gaze perfectly at tiny buttons and trying to get the Air Tap to work successfully was super annoying. You'd think they'd be able to project your fingers into 3d space from your approximate eye location.
Glad they've revisited those flaws!

To be fair, it was state of the art... five years ago. HoloLens 1 was an amazing feat of engineering. Yes, it was a terrible user experience, but we wouldn't have the latest hardware without it.
As for projecting the fingers, it is possible. It's just not a great experience. Nose-pointer is a (application level) compromise. I've built apps in HL1 where direct hand gestures are essential. And it's definitely a master interface. It's not something you can easily train new users on.

#6Very happy to see the holo lens improving. I'm hoping this can bring a growth in labour jobs which require technical skill for individuals who do not have any high-level training (e.g. electricians or mechanics). From a safety perspective, there is a lot that can be learned in envirnments like power plants, oil refineries or factories.

Right?

The author discusses square degrees, but then makes the following statement:
"if we stack 19 Hololens 2 units perfectly, we have ourselves a fully Holographic sphere)...So don’t get hyped on that!"
...and it's rediculous assesments like this (e.g., which have no bearing on a viable AR display) that cause me to stop reading.

#9I wonder how text rendering performs. If it's good, a Hololens 2 IDE would be an improvement over a laptop for working while traveling.

Its going to be too hard to apply to non-standard locations. This thing is just hardware, its going to need a lot of software and developers behind the applications.
I'd foresee it more as a tool to use in fast food restaurants and similar high-turnover manual industries. Assuming you had trained people front of house and for cleanup, you could throw one of these things on anyone and having them working back of house immediately.
