Victor Castroll, an analyst with Valcent Financial Group, says Apple sold 51,000 iPads within two hours after the device went on sale.

As noted by "CNN Money" (http://brainstormtech.blogs.fortune.cnn.com/2010/03/12/apple-sells-50000...), his estimate -- which is adjusted for the roughly 15,000 online orders that come in a typical day -- jibes with a 20,000-per-hour figure published earlier by "Silicon Alley Insider" (http://www.businessinsider.com/is-apple-selling-20000-ipads-an-hour-2010-3) and the photo sharing Phanfare site (http://blog.phanfare.com/2010/03/apple-is-currently-selling-20000-ipads-...). That number was based on two sales made within 30 minutes that were 10,000 order numbers apart.
