Maybe Google really does have something here -- in just two days, they have leapfrogged Opera in market share, and have their eyes set on bigger fish. I would have thought that Google's foray into the browser market would have taken a bit more time to develop, but it seems that adoption has been extremely rapid. According to TechCrunch, most users are coming from Internet Explorer, not Firefox.
Microsoft must be worried, or at least they should be -- imagine how embarrassing it would be if Google begins to dominate IE in short order, and Microsoft continues to lose search market share regardless how hard they try.
I would be interested in hearing your honest opinion on Chrome -- personally, I have made the switch, and I am definitely not looking back. It's everything I need, and nothing I don't. It's so important for newly launched services and applications leave a good taste in the mouths of early adopters -- unfortunately, that is usually an extremely hard thing to accomplish.
