Google's numbers presumably only come from tablets running Honeycomb accessing the Market. Which means non-Honeycomb tablets (which have been out a lot longer, have greater penetration in non-US lands, etc etc) aren't counted.<p>I can't find any recent stats, but as of March 2011, the Nook Color sold 3 million units. Way ahead of the 0.9mil quoted in the article, and it's only for one device.
