After less than a month on the market, Research In Motion has reportedly had to recall nearly 1,000 faulty BlackBerry PlayBooks, the Canada-based company's debut media tablet.

This latest incident continues the saga of RIM's entrance into the burgeoning tablet market – an entrance that, to this point, has been less than graceful.

According to a memo to Staples and published by Engadget, approximately 900 of RIM's tablets contained some sort of glitch with the mobile operating system. While the document does not specify what the malfunction is, it does reveal that the problem seems to occur on the 16-gigabyte model.

CNET reported that RIM has confirmed the recall, stating that the problem may cause the tablets to be unable to upload software properly. The company also said the majority of tablets had not yet been sold to customers, but were still in the distribution channel.

"RIM is working to replace the affected devices," the company said in a statement.

After much anticipation, the PlayBook hit the market in mid-April to mixed reviews. However, given RIM's experience in the enterprise market and the wealth of mobile accessories slated to enhance the tablet's performance, some experts have predicted the PlayBook may eventually emerge as the tablet of choice for the workplace.
