I image you'd need both hands to replace two mouse buttons and a scroller, and to me that seems to break the deal.

I don't know why but reposting seems to happen a lot on HackerNews. It's not the fact that they get reposted that's bugging me but the fact that the same people upvote them. Why would you still upvote something if you know you've seen it before on HN? It eludes me.
Earlier quoted context omitted.
You are implying hand waving all around with such use case. I, for instance, imagine it as replacement for trackpad - I type happily on my keyboard, and I just do some slight gestures for scrolling, switching, closing, minimizing and pointing. And all while keeping my hands close to home row. It's even in similar form factor as trackpads! I don't know why everyone thinks it will be like signaling on an airport or doi…
Why is it more difficult to do those gestures on the trackpad? The trackpad is closer to your keyboard and it is very quick to switch between the two.
The film version of Minority Report was not a model for practical or usable interface design. Millions of years of evolution have built our brains and bodies for interacting with things that provide physical feedback when we touch them. Waving a pencil in the air, "manipulating" an invisible item and looking for visual feedback from a screen, these are not good experiences. Even if you discount the "gorilla arm syndrome" that StavrosK quite rightly points out here, the fatigue of trying to perform fine and accurate motion without physical stimuli for your hands and fingers to respond to is significant.
I'm sorry to be a negative voice in the face of innovation, but this really does feel like a technology in search of a problem. What worries me greatly is that it has a remarkably high "cool factor" that would be excellent in short demos, and could be easily pitched to companies looking for a flashy feature to get a leg up on the competition. We were saddled with some dubious decisions at the dawn of the GUI age, and we're just starting to lose them as we enter the Direct Manipulation age of interfaces. Please don't let this concept of feedback-free hand gestures become a paradigm that we're stuck with in the future.
Please, for the love of Jef Raskin and Henry Dreyfuss and Don Norman and all that is human factors, no. The film version of Minority Report was not a model for practical or usable interface design.

I'm not convinced the lack of tactile feedback is a problem provided there is very good visual feedback. Do you have any studies to this point?
Furthermore, I think basic pointing and pinching are only the beginning of the capabilities this system can provide. More complex hand signals, or even face, body and posture signals could drastically increase the bandwidth of human/computer interaction, even by supplementing a keyboard.
Whenever I see something like this, I immediately think of gorilla arm syndrome. There's a reason I was saying they will never become widespread when all my friends were screaming about Minority Report-style interfaces (ever since Minority Report).
Let's be more creative than that. Think about using it as an alternate input in spaces that a physical keyboard/mouse isn't appropriate, and also 'short term computing'.
Will this replace input on your workstation? I doubt it- but what about a large map that's installed in a public place? What about some sort of restroom or medical computing device where you'd rather not touch the surface that someone else just touched? You're not going to sit there 12 hours a day. You're going to pull up the map in the hospital and zoom/pan around on it. Why do we need another surface to clean? And in 15 seconds- you're done. No gorilla arm syndrome, no pain, and no real learning curve.

If you look at it, it's quite sensitive enough to follow finger motions, not only whole hand motions. So it could even follow your fingers as your hands rest on a desk.

While I do think tactile feedback is extremely important, I won't discount the ability for humans to adapt. Should a compelling enough system be developed, I imagine any person who desires would learn and adapt to a system -- the problem here is getting the gross majority of users to adapt to it.
There's obviously going to be a lot of backlash against a product like this (and equal amounts excitement). I think the problem here is after such a well publicized film, everyone assumes tech like this is going after a Minority Report type paradigm. While they definitley have to (somewhat) pitch it like that, I'm very excited to see different ways that something like this can be used. It definitely seems like a great step forward.

Evidence for that is what?
