We found the BlackBerry PlayBook to be a pretty solid piece of hardware, but it seems there was a problem batch -- an inside source tells us that nearly 1,000 faulty tablets were shipped to Staples, and now they're being recalled. We're hoping that Staples (and any other affected retailers) will reach out to customers and inform them of the problem right away, but just in case that doesn't happen, we've compiled a searchable spreadsheet of all 935 alleged serial numbers for you to check against your own. Find it right after the break.RIM tells Crackberry that the faulty batch of the 16GB tablets was indeed limited to the approximately 1,000 units described here, and that they had a faulty build of the OS "that may result in the devices being unable to properly load software upon initial set-up." Furthermore, the company says that only a few went out to customers and that most are still in distribution, so with any luck you'll never have to deal with this problem to begin with.
