Google was going to be an interesting case of a large company hiring people both from the embedded world and also the existing Linux development community and then producing an embedded device that was intended to compete with the very best existing platforms. I had high hopes that this combination of factors would result in the Linux community as a whole having a better idea what the constraints and requirements for high-quality power management in the embedded world were, rather than us ending up with another pile of vendor code sitting on an FTP site somewhere in Taiwan that implements its power management by passing tokenised dead mice through a wormhole.
To a certain extent, my hopes were fulfilled. We got a git server in California.
