The amazon tablet sounds like a great deal, and its cases like this that really show how much of a powerful corporation apple has become. Personally, I have not heard of the amazon tablet; either amazon needs to do a better job at advertising or apple products are just so popular that they simply overshadow most products from its competitors. Amazon’s penetration pricing for its tablet is an obvious attempt to gain some market share from a apple dominated market. However, apple has gained an almost monopoly status which allow them to advertise very aggressively with the amount of revenue they acquired from all the sales they have made from their recent line of famous products including iphone and ipods, allowing very little room for competitors to fit their way in the market.
