Well, the impact I think is bigger than just having another browser. It's the first salvo in creating the Web browser as the "operating system." While that may seem like just another tech trend, the end result is likely to be Internet devices which don't require significant hardware, since all of the applications are running on the Web. Potentially, this will reduce the physical cost of computing dramatically, allowing for much more use and far less maintenance.
I was reading different articles about Chrome. Since I speak more than one language I wanted to get some perspective from other users in other countries. I agree with you that the impact will bigger than just having another browser. In addition to speed, multi screens...it could change the way we use computing.
