Here's a minor surprise: Android slipping at all in US market share. Although it saw just a tiny drop of two tenths of a point from where it was in March, and still saw a gain over January, Google's platform was down to 50.8 percent in April. Nothing dramatic enough to make Mountain View worry, as such, but definitely a sharp break from the rapid growth of last year. Apple could meanwhile claim a small victory for the month as a result by continuing to grow -- even if we wouldn't call its 31.4 percent iPhone share a revolution. Of the other platforms, only Microsoft had anything to crow about, as the Lumia 900 launch brought Windows Phone back just over the four percent mark.
