A new Nielsen study has identified some of the demographics of iPad owners, and made some significant contrasts with other devices, Fortune notes. Of 400 surveyed iPad owners, a large majority -- 65 percent -- were found to be male. The imbalance was paralleled only in a group of Sony PSP owners, which slanted 62 percent towards males. Another e-book reader, the Amazon Kindle, only recorded a 52 percent male bias.
