Following the breaking news this morning that he's leaving the Android unit, The Wall Street Journal has published Andy Rubin's farewell letter to Android partners.
Here's a snippet from the letter:
In November of 2007 we announced the Open Handset Alliance with 34 founding members. Today, I'm grateful to the over 85 OHA members who have helped us build Android and drive innovation at such an incredible pace. The Android ecosystem has seen tremendous growth since the launch of the very first Android device in October 2008. The volume and variety of Android devices exceeds even my most optimistic expectations - over 750 million compatible devices and counting!
For reference, Rubin co-founded Android in 2003 before it was picked up by Google in 2005.
At that point, he has been senior vice president and the head of the mobile operating system unit until CEO Larry Page announced today that Rubin was stepping down.
Rubin will be replaced by Sundar Pichai, senior vice president of Chrome and Apps, as Google's two operating systems move closer together.
It's important to stipulate that this is not a farewell letter to the company.
Describing himself as an "entreprenuer at heart," Rubin makes it clear at the end of his memo by specifying that "now is the right time for me to start a new chapter within Google."
