Members of the AAPL Sanity Board set out with the task of determining how many iPads were sold in the first day of ordering came back with an interesting number: 120,000. The statistic was compiled using information regarding 48 orders and serial numbers for the iPad.
An Apple Expert Philip Elmer-DeWitt said that the information sounded correct and coincides with the supposed popularity of the iPad. Also of note is that a good majority of the orders were for the WiFi only models and not the 3G models. Right now, Apple is limiting the amount of iPad units to two per person.
