We’ve really gotta hand it to Apple. Just 28 days into the availability of the iPad, and they’ve already sold over one million units. That’s 300,000 on day one, 450,000 within five days, and then another deluge with the launch of the iPad 3G model this past Friday. According to Apple, iPad users have downloaded over 12 million apps, and over 1.5 million ebooks from the iBookstore. Yup, the iPad has become another money printing machine for the company. Oh, and in case you were wondering, it took the iPhone 74 days to sell a million.
