Apple's iPad was released to the world three years ago on April 3, 2010.

At the time, a lot of people were underwhelmed. We even called it a "big yawn," and said, "Jobs introduced something that is probably going to sell in the range of a few million units this year, much closer to one of the company's Macs than its runaway hits like the iPod and iPhone. Not the company's next huge growth story."

Oops. We got that one very wrong!

In the three years since the iPad launched, it's changed everything. It truly was a revolutionary device. Here's a quick run down.

Apple has sold 121 million iPads, totalling $67.7 billion in sales, and it's expected to have sold 18 million more this quarter worth $8 billion.
