According to Chitkita Lads Apple has sold more than 1 million iPads. If that is correct, it has taken 21 days for Apple to sell 1 million ipads.
Comparing that to the first iPhone, it took 74 days to sell 1 million iPhones. There is no doubt that the iPad is a runaway success. 
The numbers by Chitika Labs are only an estimate but if they are close the we can expect a press release from Apple soon.
Here is how Chitika are getting their numbers.
The Chitika Research team tapped our genius engineer Gui to build us a page that showed just how many iPads were out there browsing the World Wide Web. Here’s how we did it:
- We count how many new, unique iPads we see coming through the Chitika advertising network
- We multiply that by how much of the Internet we see at any given time to figure out how many iPads in total are out there
- We look at where iPad traffic is coming from by state
