Amazon reports e-books are outselling hardcovers

dingen writes: Amazon reports that for every 100 hardcover book they've sold in the last quarter, 143 e-books for Kindle were purchased through their service. The difference was even larger this month, with e-books outselling hardcovers 1.8 to 1.

It seems like e-books are really breaking through, altough then again, who purchases hardcover books anyway?
