Your title makes it sound like there is just one video out there making this claim. That's the only reason I took issue with it, because it misleads people slightly. Someone just cross-posted in the thread I just made about the qualcomm port saying offhand that the other two videos I was discussing were faked. I don't think they are, and in any case they're entirely different from the video you're talking about.
AndroidGuy31 made a fake vid. More impressive is that there are now 3 videos of a functional android 2.2.1 port on youtube, one android touchpad listed on ebay, and one guy offering to image his for the community on a dev board. So either 3 people all spontaneously decided to hoax people with the same Android builds and situations, or maybe HP really did let some of the QI tablets out into the wild during this firesale, during which their shipping could barely handle demand. I really don't think the guys at the HP warehouses were paying attention what stack the box came from.
It's your thread though, I won't bring it up again. Just figured I'd ask since it'd be helpful.
