Barnes & Noble may have doubled its tablet shipments in the fall. Having shipped over 800,000 Nook Color devices in the summer, the company was said by part suppliers speaking to Digitimes late Thursday to be delivering a combination of 1.5 million Android-based devices during the fall. About 1.1 million of those would be the new Nook Tablet, with the remaining 400,000 being the price-discounted Color.
