A new Gadget Census study, released by Retrevo, has looked into substantive differences between habits of iPhone, Android and Blackberry users on both their handsets and other high-tech devices. Android users were deemed the most "cutting edge," with iPhone users positioned as young, satisfied consumers and Blackberry owners as older and tending to hang on to older technology for longer periods of time. Mac owners tended to have some PCs in the house, while PC-dominated households rarely had Macs around.
