Quantcast, who measure traffic on most major sites, have posted their findings on mobile device usage. It won’t surprise anyone that for May, Apple is way out in front of everyone.
But the numbers aren’t all rosy for Apple AAPL. Even with the release of its very popular iPad and two-million devices shipped in the first two months, Android is catching up, and significantly.
In January of 2009, the iPhoneOS had almost 80% of the market. Over the past year an a half (since the Android platform launched), that has eroded to 58.8%. Meanwhile, Android has come from almost nothing to last month getting 20% of the North American web consumption pie.
While te rest of the market was mostly flat for the first half of 2010, Android nabbed 5% of the market from the iPhone OS. That’s pretty incredible considering Apple’s success wit the iPad.
