I managed to miss this one yesterday. I actually passed through the Qualcomm booth twice and it wasn't there either time.
This isn't a product prototype, just a screen demo. I don't know who shot the video, sorry.
In other news, Pocketbook will have a press conference at 11am today.They've been giving me the run around on exactly what they plan to announce, but it's probably the new Mirasol ereader.
