If you want to understand the major challenges that BlackBerry faces in the American market, look no further than a new survey commissioned by MKM Partners showing that most Americans don’t even know that BlackBerry 10 has launched yet.

Even if more Americans knew, I doubt they’d care very much.

68 percent of those polled said they have absolutely no interest in buying a BlackBerry.

This launch is the very definition of a day late and a dollar short.
