This could be an example of Google doing no evil. But more likely it's Google management having a firm grasp on history and knowing that a small band of zealous opponents could effectively derail their grand design.
If you put together Google Apps Premier Edition, Google Gears and Chrome, you have the makings of an entire suite of products, from applications to development tools, plus a single browser to bind them all. Even the Google Android operating system fits into this paradigm.
The only thing missing is an operating system. Google executives argue that the Web is the only operating system it needs, and that would be true if Google weren't trying to build a hegemon.
But no one owns the Web, and if the Web is Google's de facto operating system, then it is dependent on a system that it doesn't control. And it will remain dependent on other vendors of proprietary systems for off-line access.
Joe Wilcox writes an insightful parody of Dickens' Christmas Carol, but says quite seriously, "A Google OS is inevitable." I agree with him.
