It’s not exactly an e-book reader of its own as previously rumored , but Barnes & Noble’s announced an alliance with Plastic Logic in which it’ll serve as the “exclusive eBookstore provider” to the long-in-development e-reader, which unless we’re playing with semantics here means any and all digital literature you’re wanting to purchase on-device will have to come from BN. According to the press release, downloads from Google’s public domain archives will also be made available gratis , and as for the enigmatic 8.5 x 11-inch slate, it’s still reportedly on track for an early 2010 launch . Much in the vein of Amazon’s more recent maneuvers , the ole’ brick-and-mortar retailer is taking what it’s calling a device-agnostic approach, with apps already available for iPhone and iPod touch, Blackberry, Windows, and OS X
