Best Buy’s (BBYInsignia Flex Tablet teased last week will cost between $239 and $259, nearly half the price of an Apple (AAPL) iPad, according to Reuters’ sources. The 9.7-inch tablet launches on November 11th and is Best Buy’s first Insignia-branded tablet. It will have a 1GHz dual-core processor, 10 hours of battery life on a single charge and Android 4.0 Ice Cream Sandwich. Reuters adds that the slate will also have a front-facing camera for video chats and a weight of only 1.45 pounds. Best Buy still hasn’t released any details on how much memory the Insignia Flex Tablet will have or whether or not it will have any kind of memory card slot for expansion.
