Are two (or more) versions of an OS better than one? Some say yes, and it looks like you can now count Google among them. Speaking at this week's RSA Conference, Google software security engineer Will Drewry revealed, seemingly for the first, that Google will be releasing a "business version" of Chrome OS for netbooks sometime in 2011. Details on it are still pretty light at the moment, as you might expect, but it will supposedly offer more "management muscle" than the consumer version. Drewry did drop a few more details about Chrome OS for netbooks in general, however, including the interesting tidbit that you'll be able to enable a development mode by flipping a switch located under the battery.
