Apparently now shipping! See
here (Engadget) and
here (Archos).
Actually, the "purchase" option is not yet live at Archos' website, but it does give the pricing as $274.99 for 8GB, $349.99 for 250GB.
Overall looks very appealing! More features than the Nook Color for only a touch more cash, and way cheaper than the Samsung Galaxy Tab.
Now if only the performance is there . . . something that has been a downfall for Archos in the past . . .
