How long after its April 3, 2010 release did Apple Stores sell their millionth iPad?
After months of speculation and some less-than-favorable initial feedback, the iPad, Apple's long-rumored tablet computer, was released to a salivating public on April 3, 2010. And while some early reviewers had panned the new product, consumer demand was insatiable. The iPad sold faster than any product in Apple history, selling its millionth unit a mere 28 days after its release, far surpassing even the iPhone, itself considered a blockbuster for selling one million units in 74 days.
