Quantcast reports that while iPhones still own the mobile web market, Android devices are quickly making up ground. A year ago the iPhone’s iOS platform owned nearly 70 percent of the market while Android hovered below 10 percent. Last month iOS slumped to 56 percent while Android clawed its way up to 25 percent.

If this trend keeps up, Android will own close to 100 percent of the market by the time the decade is half over, while iOS usage will drop into the negative percentages.

Ridiculous extrapolations aside, when and if do you think Google’s smartphone bloodhound will catch Apple, and what does Apple need to do to maintain its domination?
