????All happy Kindle Fire customers, to paraphrase Tolstoy, are the same. Unhappy customers, however, are unhappy in their own way.
????To get a feel for what makes them unhappy -- and how unhappy they are -- we spent some time Saturday morning reading the Kindle Fire feedback on Amazon.com.
????There were 3,678 write-ups in all, nearly half of them (47%) glowing five-star reviews that basically said the same thing (Typical headline: "Outstanding value at $199").
????What interested us, however, were the 491 (13.3%) one-star reviews. They are relevant because the number of Kindle Fires being returned to the store is likely to be an undisclosed material factor in Amazon's results this quarter.
