Barnes & Noble (BKS +6%) is surging as investors show their appreciation of Apple's decision to start iPad Mini pricing at $329. B&N new 7" Nook HD sells for $199-$229, while the 9" Nook HD+ goes for $269-$299. Shares sold off yesterday on Apple-related worries. Texas Instruments (TXN -0.4%), which (for now) supplies processors for both the Nook and Kindle lines, could be an indirect beneficiary of the Mini's pricing. Ditto Nvidia (NVDA), whose processors go into the Nexus 7 and other Android tablets.
