My university just happened to have a Microsoft Hololens 2 that I was able to try. The guys there said that it was in the region of £2k, and I'd assume that's after an education discount.

Thoughts:

1. As with most Microsoft hardware products I know exist, Hololens looked nicely designed.
2. I like the rear dial to tighten over the head, and the optics can be swivelled out of the way when putting it on/taking it off.
3. The first thing I noticed was the light non-uniformity. I think it was on this website but I remember seeing an image that showed how the brightness noticably decreases closer to the edges of the FOV.
4. The FOV was better than expected. I really think it's because there's less light on the edges, so the projected image more guadually comes into view instead of a sharp boundary.
5. The 3d... didn't seem that 3D. Like there was depth but it was more like a 3DS. I assume that this was the thing that VR users talk about where everything, no matter if it's close or far, is at the same focus. 
   1. I quickly compared the view that my left and right eyes were seeing, and the difference was noticable but small. Perhaps I was supposed to set IPD or something to that effect, but I think dual cloned images for TyMist is sill better than 1 eye only.
6. I initially noticed how choppy the hand tracking was, but not how fluid the air-drawn text in the background was. I don't plan on any hand tracking so I'm more interested in the FPS needed to achieve the latter. Googling seems like 60fps, which is suprising.
7. The experience was cool, but not sharp. I just searched and the Hololens 2 has a PPD of 47.
8. The brightness of the world is higher than the 2 way mirror.
