MacDailyNews notes that multiple iPad customers who placed pre-orders for Wi-Fi iPad models and are looking to change those orders to in-store pickup reservations have been told by Apple representatives that customer response to the iPad has been "so overwhelming" that newly-placed reservations made not be available on the launch day of April 3rd.
iPad pre-orders have reportedly been brisk and in-store pickup reservations are likely similarly strong. We've heard that one non-flagship store had already seen nearly 100 reservations for Wi-Fi iPads as of earlier this afternoon, divided roughly equally among the three capacities although weakest in the mid-level 32 GB model.Multiple iPad buyers have been told that in order to do such a change, the delivery order would have to be cancelled and a new in-store pickup order completed, but that iPad orders (which began this morning at 8:30am EST) have been "so overwhelming" that new iPad orders may not be available for in-store pickup on April 3.
With approximately 220 U.S. retail stores, Apple may consequently have received on the order of 20,000 reservations in addition to the tens of thousands of pre-orders in the first six hours of availability. It is impossible, however, to extrapolate performance from a single data point with any real degree of accuracy, and so observers will undoubtedly continue to try to piece together various pieces of information to develop a picture of early iPad sales.
