Many people weren't sure what to make of the Apple iPad when it was introduced by Steve Jobs in January. The iPad was meant to dive into a market that has largely failed to gain traction due to the use of Windows-based tablets and convertible notebooks that were never built from the ground up for touch-based input.

However, Jobs must be grinning all the way to the bank because his "magical" iPad has indeed found an audience and is continuing to burn up the sales charts. Apple sold 300,000 Wi-Fi-only iPads on launch day, 450,000 by the first week, and 500,000 within two weeks of launch.

Now that the iPad 3G is finally shipping, Apple has seen another uptick in sales for its latest iPhone OS device. Apple is now touting that it has sold one million iPads in just 28 days on the market.

“One million iPads in 28 days—that’s less than half of the 74 days it took to achieve this milestone with iPhone,” said Apple CEO Steve Jobs.

Apple also made it known that over 1.5 million eBooks have been downloaded from iBookStore and over 12 million apps have been downloaded by iPad users from the App Store.

Jobs continued, throwing in a but more praise on his "magical" tablet. “Demand continues to exceed supply and we’re working hard to get this magical product into the hands of even more customers.”

Apple's iPad starts at $499 for a 16GB Wi-Fi model and tops out at $829 for a 64GB model with 3G connectivity.
