I see this technology used in the following manner:
The laptop, while closed, looks exactly like the 15.4 inch macbook, although thinner.
However, when you open this thing up, BOTH SIDES of the computer is the screen, meaning there's no keyboard or anything. OLED technology allows for flexible displays, so this can happen. You can open up the screen to have a gorgeous 20"+ widescreen display laptop to be used for the gesture user interface, of it can be closed half way like a "regular" laptop, with the botton side of the screen turning into a visual keyboard and mouse.
If they really want to go crazy, they can allow a tablet "flip" option to have a very portable table-like laptop with the gesture interface.
This can be really amazing. I can just see myself going thorugh my digital book library in PDF with with this gesture user interface (BTW, isn't it cool that it still remains GUI as initials?

). Delicious library can be so cool for this type of thing.
Oh, one more thing: Is it just me, or does this video of sorting through pictures looks amazingly like Apeture? check out the "light table" feature on Apple site's video compared to the feature we see in this demo video. It looks like its exactly the same. How cool will it be for photographers to actually have an LCD light table that they can sort through using the Gesture User Interface?
