Just to be fair his point is valid on the browser (though I agree with you that everything else he said is utterly false). But I'd defend Google on even that.

Just to be fair his point is valid on the browser (though I agree with you that everything else he said is utterly false). But I'd defend Google on even that. The browser is the core of ChromeOS so I don't think they can allow it to be replaced. But what they can do is make Chrome the most standards compliant browser out there and that's exactly what they've been doing. So while you are locked into the Chrome browser in ChromeOS you could easily go back to Windows and Mozilla and take anything you created there with you (not to mention the Chrome browser is built on an open source browser engine)
