Apple’s iOS might be in the most dominant position when it comes to mobile web traffic in North America, but according to Quantcast, it’s Google’s Android that has been fairing best as of late. From May 2009 to May 2010, iOS traffic fell 8.1% while Android saw a 12.2% increase. Impressive for sure, but that isn’t even the best example of the explosive growth Android is currently benefiting from. During the seventeen months between January 2009 and May 2010, iOS Ā dropped 16% at the expense of Android which climbed 15% with the two now standing at 59% and 20% respectively. The accuracy of these figures are a little bit questionable as the data does not appear to readily reflect data consumed by applications. On the other hand, this data was collected well after the launch of both the iPad and iPad 3G but before the EVO 4G even hit the market. Regardless, we think it’s easy enough to draw an accurate conclusion about what’s going on here: Android is starting to take generous bites out of Apple.
