HoloLens is cool but most of the HoloLens applications you write will be consumed on the $299 software-compatible Mixed Reality headsets that ship later this year (it's amazing how few people are paying attention to this announcement - Microsoft uses Mixed Reality as its branding but these are basically high end VR headsets with integrated tracking for a third the price of Rift and Vive devices)[0][1]

From an application developer's perspective, the only difference between HoloLens coding and Mixed Reality coding is that when constructing 3D scenes your HoloLens app should have a transparent background so the person can see their room through the viewport because that's what they're buying the expensive headset for and in Mixed Reality you should have an opaque background because it's VR not AR.

The really big thing though is that $299 is roughly what you'd otherwise pay for a pair of big monitors. Full on virtual desktop support with floating windows for these devices is being shipped to every Windows 10 machine starting this week via Windows Update with the intent being you don't need old-school monitors just work in the headset, or with your monitors, or however you want.

Windows now has (or will shortly depending on your Windows Update timing) a built-in developer mode simulator for application testing of Mixed Reality code without a physical headset. The simulator is still a little buggy and incompletely undocumented (remember to shut it off when you're not using it) but it's pretty incredible and more than enough to start building and testing applications.

How well will this work though? Virtual desktops exist for the Oculus Rift and the Vive but from what I understand, the limited resolution doesn't make it a great experience, and can't really replace monitors yet for text heavy work.

You're mixing up $300 VR headsets with AR headsets.

It's not amazing because they're not showing anything except what appear to be fake, marketing videos. They've always been cagey with the HoloLens and what it was actually like and it looks like they're continuing down that line.

Please check the links on my post, and the places where I discuss the differences between HoloLens as AR and Mixed Reality as VR.

I'll also add I'm not sure what you mean by "they're always cagey with the HoloLens" it's been a shipping device for about a year now, they're available in the wild, lots of us outside of Microsoft have plenty of time in the HoloLens. The suggestion that they've been cagey about what's coming for the Mixed Reality headsets is similarly nonsense. If you want to stay a Microsoft hater because of something some guy said about Java more than 20 years ago, that's totally your privilege, I personally prefer to work in the present.

Please link to any video from Microsoft that shows an actual, simluated view of wearing a current generation HoloLens.. I've been looking, still haven't found one. All I can find are marketing videos that show fantastical visions of what AR will look like some day but not today.
Random video from first page of a google search for hololens capture, someone somewhere in Asia is my guess, it's easy to shoot this kind of stuff when you have a hololens and Microsoft recently released an open source hardware kit for people who want to make more serious video captures.

There's plenty more, but honestly if an LMGTFY link like this can answer your question it sounds like you're actively trying to keep yourself from finding out what's going on. There are no conspiracies here, it's just tech, it works, it's very cool, and there are even fully functional simulators/emulators allowing you to code without access to the devices. It's a shame you're so sure there's something wrong that you're preventing yourself from getting involved with something that clearly interests you.

[edit] I see now you said you wanted a video "from microsoft" - that's in the very first video hit searching for hololens capture[0]. This video has other stuff in it as well, including discussion of an open source hardware and software system for making hololens captures, but there is absolutely straight hololens capture video in the link, just like in the other link I sent. Again, it feels like you're trying hard to not let yourself find or see this stuff.

You're too caught up in it. Take a breath, read what's being written, then respond.

The reason I asked for video from Microsoft is because users consistently crop the views to only show the postage stamp AR view HoloLens offers and presents it as the full video which is a misrepresentation of what HoloLens is capable of. Also, that second video doesn't actually include any video from the HoloLens from a wearer's perspective but thanks for trying.

I don't want to interact with you anymore.

> that second video doesn't actually include any video from the HoloLens from a wearer's perspective

45 seconds into the clip on the verge site are four separate captures shot by the HoloLens showing the wearer's perspective, and the other clip is 100% user POV shot by the HoloLens. The verge clip is produced by Microsoft, the other clip by a user. Neither the user nor Microsoft cropped the HoloLens footage, both clips were shot with the integrated HoloLens camera which is tuned to match the active field of view of the headset. The rest of the verge clip shows how to build an open source capture device capable of recording a wider field of view at higher capture camera resolution and shows video shot using that system with a DSLR and a HoloLens. There is no "misrepresentation of what HoloLens is capable of" in either of those videos.

The first video linked is a very accurate representation of the users view. We have a current gen model at my company.

It's not vaporware, though you may not be able to find the exact videos you personally are looking for. Maybe that means it's just not for you. No bigs.

Are you implying hololens could replace my monitors (in a practical sense I mean)?

I have to admit, if the resolution was good enough (the equivalent of 1920x1024 at arm's length would be sufficient to my mind), I'd be quite OK with this. Virtually unlimited screen space for tiling applications would be pretty awesome.

One of the biggest problems I run into is even with a 30" 4k display, I'm always out of room to run concurrent windows.

You'd need like a 6k display to even start getting close to the 1920x1024 at arm's length equivalence. That's at least a generation or two ahead of where we're at today. That's why all this Mixed Reality stuff coming out of Microsoft today is just so much talk.

I'm not arguing against them working on it, there should be a foundation but we're currently at the equivalent of the late-90s, early 2000s VR devices when it comes to HoloLens and AR.

If you've not worn a HoloLens, I think you'll be surprised. There are plenty of things to complain about with the HoloLens but the resolution is amazing.
I'm fascinated by the downvote someone gave the parent, because I've never heard anyone complain about the resolution on the HoloLens after using it. If you're still in the thread and are able to discuss the scenarios where resolution was a problem, you have me curious.
Because the discussion was about replacing physical monitors, not complaining about the resolution. You're jumping at shadows.
That's where Microsoft is headed. I've only spent a few days that way (others have gone much longer) and it definitely made me a believer. These devices only run the newer UWP apps natively but worst case use Remote Desktop or VNC as a wrapper to pull up your non-UWP apps in the goggles.
I would really like to dispense with my monitor(s) and plaster big virtual monitors over the walls of my cube. But at this point, I really doubt that the hardware is usable for that use case (low resolution, weight). I'd love to be proven wrong.
CastAR might let you do that, to a limited extent. They work by projecting stereoscopic light on to retro-reflective material. However, it depends on the resolution of their projectors and if you can some how get your computer's video to them(from the sounds of it, the current generation is an all-in-one device).
HoloLens resolution is absolutely there today.
It's not, it's only really 720p at a fixed focal distance. The display does a great job of aliasing with extra light points but there is no substitute for pure pixels. Dense text and symbols/code is not a great experience.
