Thank you for the correction; however, the Kindle Fire alone has sold at least 2 million, which is still relatively good. (http://www.pcworld.com/article/247097/kindle_fire_helps_amazon_set_holiday_sales_record.html)
Again, that's not a hard number, just speculation on sales of the Fire so far (since its introduction 13 weeks ago). I for one, am surprised at such a low number. It's a decent $200 device and if there's an enormous market for small-format tablets then I would have expected this to sell like hotcakes.
