MSFT might, just might, not be quite as dead as we thought.
A couple of times, I didn't find something in bing, switched back to google.... and couldn't find it either. So I guess you could say that, provisionally, I'm sold.
It hasn't found any better results than Google yet, but the interface etc, makes it much more useful than Yahoo.
I don't see any search engine replacing Google for me though, its just too ingrained in me. And then there is the firefox aspect, where my first search pretty much goes to Google by default
Maybe I just read too much Seth Godin, but I think this is huge.
