They were discussing it this morning on NPR. It doesn't sound like they expect it to make a big dent in Microsoft's market share. What they did predict was that if its new technology proves itself then we should see Microsoft adapt some of the same features to Explorer - particularly the speed features.
Check what I just saw on a Thread in one of our sister Communities: Chrome Will Log Every Keystroke.
Despite being scared by the transvestite I thought it was interesting that they are reserving so many rights. I see it that they are going to get people in because of the nice clean browser then bombard them with the same junk Microsoft does now.
I personally would shut off the suggestion function in the browser I never have liked it in any browser.
