I believe that would be 3,000,000 in five months or as the story says, 600,000-700,000 a month. This and other sources credit B&N with about half of the tablet market, meaning apparently that it is in competition more with Apple than with Amazon, which I find interesting. I'm still waiting for Amazon to come up with something, as even though they get sales on anything that can run an Amazon app, color definitely increases sales of the devices. Me, I have neither iPad nor NC, and though I'm doing fine with my "classic" Nook, I'm saving up my pennies for color.
