I read an interesting articles on Forbes.com about the popularity of devices for reading digitally. In the Forbes.com article, it says that more people own a Kindle than any other digital reader, including Apple's iPad. But with the popularity of tablets, eReader sales are predicted to take a hit. Over the last 3 years, tablets have had a steady rise in sales, with 1/3 of all adults owning one.
" Despite flat sales growth for e-reader sales in the U.S. overall as more Americans opt for cheap, multipurpose devices like tablet computers instead."
