Just two hours that Apple started with the presale of the iPad and already reached the sum of 51,000 iPads reserved. The estimate was derived through serial numbers. On average, 25,000 iPads per hour, something I think very few you had imagined.
Victor Castroll, Valcent Financial Group analyst and member of AAPL Sanity who was in charge of monitoring, who announced that there were 51,000 orders in two hours iPads.
Its estimate of 20,000 is consistent with the hourly iPads published earlier by Allet Silicon Insider. That number is based on two sales with 30 minutes apart and had about 10,000 serial numbers between each purchase. Remember, it is estimated that Apple has a supply of 300,000 units available for sale beginning April 3.
We also know that among members of AAPL Sanity, 25% retained a model with Wi-Fi + 3G and 25% larger 64GB model. 25% of them also ordered the two iPads.
