Android accounts for 25% of US mobile web usage0
Much of Android's success can probably be attributed to the release of a number of popular handsets over the past year, including the Droid, Evo 4G, and Samsung's Galaxy S line. Google also enjoys a significantly larger base of potential customers than Apple. While the iPhone is currently available only through AT&T, Android devices are being sold by all four major US carriers.
Neither Apple or Google's spokespeople have responded to the report yet - but if recent events are any indication, we might have some interesting press releases to read over the next few days.
