According to Chitika's latest August 2012 market share reports, Apple are absolutely dominating mobile web traffic, seeing their share of mobile traffic pass 65%. iOS completely smokes the competition, made up of Samsung, HTC, Motorola, LG, and "other".
Out of the candidates, only two of them saw growth between July and August. Apple saw 1.28 percentage points (from 63.75% to 65.03%) and Samsung saw 1.56 percentage points increased, from 10.91% to 12.47%.
But, we're seeing Samsung release more and more devices, Motorola just announced three new smartphones today, and HTC should hopefully have a comeback with more than one device in the near future. The fight isn't over, and it never will be, but it is interesting to see just how much Apple's iOS platform dominates in mobile traffic.
