Over 300,000 iPads were sold in the US by the end of Saturday, says Apple. The figure represents a combination of online orders, sales at Apple Stores and deliveries to "channel partners," meaning Best Buy and smaller resellers. Apple also notes that over 1 million apps were downloaded in the same day, along with over 250,000 books from the iBookstore. This translates to an average of three apps and somewhat less than one book per person.
