Xiaomi is a Chinese company... plenty of xenophobic, insightful, or whatever comments to cover that topic in this thread.
The story sort of hints that Barra's girlfriend was either poached by or traded-up for Sergey Brin (forgive my language, it's terribly sexist... but that little tidbit in the middle of this article is not there by accident and kinda paints that picture). Who knows? I don't... and other than being an interesting HR case study who cares?
What's completely missing from this article is how Barra impacted Android? I've seen him at I/O. Ok? So what else? He's a quick riser... must have done something... but what? What's not going to get done w/ Android now that Barra is not at Google? Perhaps that kind of information will be forthcoming.
EDIT: Spelling, grammar
