I have been pleasantly surprised with MS's newest foray on the web. I quite frequently use bing and have had very few complaints. Maybe Google shouldn't worry, but if anyone else is like me, I would say that my use of Google has really declined since I started using bing.
^ +1. Exactly my scenario as well. MS seems to have finally gotten search right, after years of trying, and they didn't even have to buy Yahoo to do it 😀.
I actually find the commercials for it entertaining, but I keep forgetting to actually use it. Google is my default in FF and opera, too easy to just use the default.
