Have only used ours a few times since we got it. I like the display tech and image stability. I dislike the incredibly narrow FOV, imprecise and cumbersome gestures, and how difficult it is to get a comfortable fit on my head. I wouldn't pursue the first generation unless they make tons of progress on FOV and fitting.

I have the opposite opinion. The gesture recognition works perfectly and its easy to wear. However the voice recognition was really flaky in my experience. (Tried integrating voice into a Unity app)

There is a trick to getting the hololens comfortable, just make sure the inner-strap is tilted ~45 degrees. This might sound obvious but I observed a lot of people just leaving the inner strap horizontal, which means a lot of weight is on the nose and the strap has to much pressure on the forehead.

As for the tech, same opinion as everyone else. Idea is awesome, works great, FOV is limiting factor.

As for development, was super easy. Unity has inbuilt support, so just press play in unity and it automatically gets sent to the Hololens.

I developed for the Hololens and wore it a lot over a couple of weeks.
