Big-box retailer Best Buy has already started preparing for the launch of the iPad, even though its release is eight days away, sources say. Workers are said to be getting briefings on important details, such as the fact that only stores with Apple Shop sections will carry the tablet at first. This means that of the over 1,000 Best Buy outlets in the US, only about 675 will have the iPad at launch. Bestbuy.com will also be missing the tablet, leaving online orders to Apple.
