Cool post, thanks. I try not to be negative but I've been a lot of cool promising technology that hasn't seen its potential realised so I tend to ground my expectations on what things have been shown to do, not what it may be able to do if they fix issues, X, Y and Z.

How about interacting with information. Wouldn't it be cool if emails appeared Harry Potter-style like flying envelopes and you can grab it and open it in front of you. Will the resolution be sufficient to make the letters readable without using a large virtual typeface size? How about responding. Virtual keyboard appears? Can you see which letters are on the keys?
I try not to get too jaded. I know I do on some things (VR because it has been tried over and over and over and over ad nauseum) but I try to give new things the benefit of the doubt. I'm still not sold that a HMD of anything will succeed in the consumer market. But being that this is target at consumer and professional markets. I'm pretty sure it'll at least succeed in the professional market. For the consumer market, will it be compelling enough to overcome your average consumer's aversion to wearing hardware on their head? I'm not betting on it. But this has potentially the best chance out of everything (I don't think VR will be able to sway the average consumer although it may get some of the hard core gamers).
Yeah, there's lots of potential here. Limited mostly by the the ideas and capability of developers combined with how accomodating the APIs and hardware are.
I want to know about text input. I'm assuming speech to text is going to be the primary means, but what happens if you have to enter a password. Will they use a "look and select" method, like the stage demo?
As many have said there's no reason you can't use a real world device for input. You could use a joystick, trackball, keyboard, tablet, laptop, PC, breathalizer (for you recovering alcoholics out there
), whatever in conjunction with the HoloLens.
Ideally they'll come up with a robust control scheme for the device itself.
There's no reason it couldn't project a keyboard onto a surface (like your arm, a wall, a table, etc.) and then you touch the appropriate places on that surface to input text. That would remove the Z axis which would be problematic with knowing exactly what your finger was hitting.
Hell, it could project anything onto say your hand, and then you touch whatever object/selection item you wanted on your hand to select something. Sure minority report style input in mid-air is cool, but something composited onto your hand and arm is still cool, and significantly more practical I would think.
Imagine you're standing in a white room and the "hologram" is being projected onto one of the walls. The "hologram" is a window playing a video clip. Parts of the frames of the video are black, or near black. How the hell is that going to work? The previous tenant in my apartment painted the living room blood red, and I have't changed it. If I use this thing in my living room, and it's displaying a hologram that's blue, is the hologram going to look purple?
The device itself is beaming light directly into your eyes. Combined with the darkened glass of the visor shield, it should allow mostly perfect color rendition except in the cases where the background light is exceedingly bright (like really shiny objects in direct sunlight).
They could also use electrochromic panels (
http://en.wikipedia.org/wiki/Smart_glass ), to adjust the transparency of the visor shield. Anything from totally transparent to almost opaque. I used electrochromic panels as an example because they only require voltage to change states although the change is relatively slow. The other technologies require no voltage in the default state, but require constant voltage in any other state.
And for outdoor uses, they could use passive smart glass that just changes transparency based on ambient light conditions.
