Research In Motion’s debut tablet has been something of a disappointment for the Waterloo, Ontario-based vendor. While the slate showed promise, it failed to offer potential users a compelling reason to choose it over the iPad or an Android tablet, and RIM would end up taking a $485 million charge in the third fiscal quarter due to unsold PlayBook inventory. Sale pricing ahead of the holidays last year¬†seemingly helped RIM and its distribution partners clear out some stock, however, as the company is once again offering discounts on its QNX-based tablet. While pricing starts at $299 rather than $199 this time around, all three PlayBook models cost $299, which means the 64GB version can be had for a deep $400 discount. RIM’s first major update for its tablet OS set to bring native email and more next month.
