Staples issued an alert to their stores, informing them that 935 BlackBerry PlayBook units were faulty. But some of those units might still be on the sales floor, rather than with a new customer. We imagine that other retailers are doing the same serial-number-scramble to ensure that they don't sell a faulty unit.
As for the actual cause of the recall, they haven't provided any information. Some users have reported typical problems like dead pixels and overheating, but we haven't heard of any catastrophic failures. So RIM's got that going for them.
