Basically, the main rivals of the Insignia Flex would be Amazon’s Kindle Fire HD tablet, the Nexus 7 from Google as well as other Android-powered tablets in the market, especially those from Samsung, and perhaps even the new iPad mini that is tipped to be announced later next week. It is reported by Reuters that the Insignia Flex will arrive in stores this coming November 11th, and will obviously be a Best Buy exclusive. What kind of hardware can we expect at a sub-$300 price point? We’re looking at a dual-core 1GHz processor, a 9.7” display, and a 10-hour battery life, all crammed into a body that tips the scales at 1.45 pounds.
