????突然之間，蘋果（Apple）的限制性產(chǎn)品策略無論是給開發(fā)者還是對用戶帶來的優(yōu)勢變得一目了然了。蘋果任何時期上市銷售的iOS設備種類都只有屈指可數(shù)的幾種iPad、iPhone和iPod touch。

????想提前知道哪些Android應用程序將在哪些設備上運行可是個難題，不過谷歌（Google）董事長埃里克?施密特對此卻輕描淡寫。開發(fā)者們紛紛抱怨Android生態(tài)系統(tǒng)的“碎片化”。不過施密特卻認為這是“差異化”。

????OpenSignalMaps網(wǎng)站展示了一副生動的互動圖表。Android產(chǎn)品的包羅萬象，從大受歡迎的三星（Samsung）蓋世SII（61,389次下載）到超過1,300種僅有一次下載的產(chǎn)品無所不有。后者都來自一些籍籍無名的產(chǎn)品，例如Concorde Tab（一款10.1英寸的匈牙利平板電腦）、Lemon P1（一款支持雙SIM卡的印度手機）、Energy Tablet i724（一款面向家庭娛樂的西班牙平板電腦）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).
