套用托尔斯泰的文字，所有幸福的Kindle Fire用户都是相同的，不幸福的则各有各的不同。

    为了切身体会他们的不幸，了解他们究竟有多么不幸，我们在周六早上抽出时间阅读了亚马逊网站（Amazon.com）上有关Kindle Fire的反馈。

    总计3,678篇用户评论，将近一半人（47%）给予了Kindle Fire五星的评价，他们的评论几乎如出一辙（最典型的标题：“199美元！物超所值”）。

    不过令我们感兴趣的是有491篇（13.3%）给出了一星评价。它们非常重要，因为亚马逊在本季度的报告中，极有可能不会公布用户退回的Kindle Fire数量。

    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.
