Interesting,the Nielsen's research in the U.S. on the profile of owners of portable devices. The data for the second quarter of 2011 show that men prefer tablets pc and women are e-readers.
Men constitute 57% of the keepers tablets and women 61% of the owners e-readers. The most interesting finding is that compared to 2010 show that Americans now prefer the more e-readers (the figure a few months ago was 46%). As for smartphones, where things are completely divided, with both sexes being represented equally.
