told us it'd be revolutionary, and if sales are the measure of a device's success, then the iPad seems to be well on track to validating its creator's bold claims. This past Friday, "just 28 days after its introduction," Apple sold its millionth iPad. 1.5 million ebooks have already been downloaded to the device, along with 12 million apps. Steve Jobs has also taken time from his busy essay-writing schedule to remind us that that's less than half of the 74 days it took to achieve the milestone with the original iPhone, and demand for the "magical" slate continues to outstrip supply. Full PR after the break.
