RIM to Recall Over 900 PlayBooks: report
The good thing is that the faulty batch of tablets was shipped to one vendor: Staples. If you didn't buy your PlayBook from Staples you have nothing to worry about. The bad thing is there's been no official announcement from either Staples or RIM, as of yet.
There's no detail on exactly what the hardware fault is, but if you did buy your PlayBook from Staples, even if you haven't seen an issue, it would still be a good idea to take a look at this list of serial numbers anyway.
Update: RIM has released a statement:
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.
