alphadogg writes "Despite the fact that it's often considered an illegal act, a sizeable percentage of the UK/US internet-using population 'borrows' unsecured Wi-Fi access. This is according to a study conducted by the group Accenture. 'The Accenture study found that computer users are still engaging in some unsafe computing practices. Nearly half of all respondents said that they used the same password for all of their online accounts, and only a quarter of them have ever encrypted files on their computers.'"
My guess is the actual figure is higher than that.
