With all the hype over the new iPhone in the last couple of weeks, the iPad has fallen off the radar of the press. But the tablet computer is flying off the shelves. Apple has sold three million iPads in 80 days. Or in other words, the company is selling a million iPads every three weeks. And the product is not even available in many other parts of the world yet, so the sales curve is likely to accelerate through the end of the year. Expect to see a lot of iPads under Christmas trees this year.
