Business Insider is reporting that approximately 91,000 iPads were sold in the first 6 hours of the presale. With the presale lasting 8 hours, they must have hit 100,000 pre-orders today. These numbers are just estimates, but still impressive.

Business Insider’s Source, Philip Elmer DeWitt, had been following the sales throughout the day. He estimated that Apple had sold 20,000 iPads in the first 2 hours, 74,000 in the first 4.5 hours, and finally 90,000 in the first 6 hours. If these numbers are any where close to accurate, then Apple must have surpassed 100,000 units by the end of the day.

Of course, these numbers are not official. They are estimates from 3rd parties. It is not known if Apple will report thier numbers right away. They usually like to announce a giant number at one of the keynotes.

Did you order your iPad today? I reserved one for pick up, so I can take part in the launch festivities. Only a few more weeks!
