If you check out engadget.com, you'll see a story on this device/hardware platform that says the video is a year or more old. The author of the blog entry also suggests that Microsoft released the video in response to Apple rumors about tomorrow's new product announcements. I don't know that there is even a release date on this type of device.

Also, the Sony e-book reader has been given a price of $350, so I would guess that this is the price point set for portable tablet style devices. In the meantime, you can get a smallish notebook computer for less than $1000; the dualcor cPc is expected at $1500, and the Oqo is $1800. It will be interesting to see where this Microsoft thing comes in in terms of price and features, and how aggressively they are interested in taking this market. This may be the kind of thing where the cost to the consumer is partially subsidized by Microsoft, like the XBox. Of course, with a gaming system, you sell games to make up profit, so the model is a little different.
