Barnes & Noble's Nook Tablet costs $249 while Amazon's Kindle Fire sells for $199. There are other differences between these two competing 7-inch tablets, of course, but for many consumers, the only one that matters is the $50 price discrepancy. In the eyes of the average shopper, both of these slates are capable of doing the same thing, so why pay 25 percent more for the Nook Tablet? Tech savvy users can answer that question by running their fingers down the spec sheets, but at the end of the day, Amazon's Kindle Fire, now the second most popular tablet in the world behind the mighty iPad, is the one people are buying. If the Nook Tablet was also priced at $199, would that still be the case?
