????突然之间，苹果（Apple）的限制性产品策略无论是给开发者还是对用户带来的优势变得一目了然了。苹果任何时期上市销售的iOS设备种类都只有屈指可数的几种iPad、iPhone和iPod touch。

????想提前知道哪些Android应用程序将在哪些设备上运行可是个难题，不过谷歌（Google）董事长埃里克?施密特对此却轻描淡写。开发者们纷纷抱怨Android生态系统的“碎片化”。不过施密特却认为这是“差异化”。

????OpenSignalMaps网站展示了一副生动的互动图表。Android产品的包罗万象，从大受欢迎的三星（Samsung）盖世SII（61,389次下载）到超过1,300种仅有一次下载的产品无所不有。后者都来自一些籍籍无名的产品，例如Concorde Tab（一款10.1英寸的匈牙利平板电脑）、Lemon P1（一款支持双SIM卡的印度手机）、Energy Tablet i724（一款面向家庭娱乐的西班牙平板电脑）等。

????Suddenly you can see the advantage -- both for developers and users -- of Apple's (AAPL) approach of limiting the number of iOS devices on sale at any time to a handful of iPads, iPhones and iPod touches.

????Google (GOOG) executive chairman Eric Schmidt downplays the challenge of knowing ahead of time which Android apps will run on which devices. Developers complain about "fragmentation" of the Android ecosystem. He suggests that they think of it, instead, as "differentiation."

????You can see a live, mouseable version of the chart at OpenSignalMaps' website here. The products represented range from the popular Samsung Galaxy SII (61,389 downloads) to more than 1,300 single downloads from relatively obscure devices such as the Concorde Tab (a 10.1-inch Hungarian tablet), the Lemon P1 (a dual SIM Indian phone), the Energy Tablet i724 (a Spanish tablet aimed at home entertainment).
