Lo and Behold I see this article:
Dell Inspiron Duo finally official, can be yours the first week of December for $549
That is the same price I was looking at for the 101z, but with an innovative flipping touch screen that allows it to be used as a tablet. If you haven't looked at the previous link and the embedded video, here is the direct link to Dell's website for the Duo with a small video of the flip screen in action:
Looks very nice and can't wait to see what else it comes with. Hoping for a really good battery life...should get it with the atom processor.
More to come...
