Remember Benedict Evans? He’s the Andreessen Horowitz partner whose 13-minute slideshow “Mobile is eating the world” was featured here a few months ago.

No matter. Evans isn’t hard to find. He writes a weekly e-mail newsletter, co-hosts an influential podcast and tweets. A lot. 62,500 tweets since 2007. To 56,700 followers.

His connection with one of Silicon Valley’s premier venture capital firms (Facebook, Skype, Twitter, etc.) gives him access to data that’s not always publicly available. Like iOS and OS X device share data as seen by Baidu, China’s leading search engine.

Happily for the rest of us, he shares it.

FOLLOW-UP: Evans says these numbers are available on Baidu’s developer site, although I couldn’t find them. “I never post anything that isn’t public!” he says.
