"RIM determined that approximately one thousand BlackBerry PlayBook tablets (16 GB) were shipped with an OS build that may result in the devices being unable to properly load software upon initial set-up.
The majority of the affected devices are still in the distribution channel and haven't reached customers. RIM is working to replace the affected devices.
In the small number of cases where a customer received a PlayBook that is unable to properly load software upon initial set-up, they can contact RIM for assistance."
So, to RIM's credit, it sounds like the problem wasn't a combustion-prone battery or a major design flaw. It also means that if you've already been using your PlayBook successfully, then you don't need to check your SKU against the list of affected units. Public relations crisis: averted.
