Naturally, we have no way of knowing if these numbers are exact as of yet. The numbers reflect over 50,000 orders placed in two hours, and the percentage of those that are iPad orders isn't clear. Considering that the iPad was just made available for pre-order today, however, and the 15K daily average noted above, it's likely the majority of orders placed this morning were indeed for the iPad. Additionally, the numbers only reflect the number of orders placed, not the number of units ordered; taken with the 2-pad maximum for today's pre-orders, the data does suggest that somewhere in the neighborhood of 50,000 iPad pre-orders were placed within two hours of its availability.
This suggests a huge demand for the device, at least among early adopters. It will be very interesting to see if this trend is repeated once the iPad is actually available in stores.
One interesting note: even if all 50,000 of those iPads were the $499 version (which is very unlikely), based on iSuppli's analysis of that unit's build cost, it means Apple gained nearly $13.5 million in
