After month, Bing's share of search market barely inches up

Essentially bing replaced msn search. If it is really better than the competition it will be a game of attrition to get people to try it and switch permanently.

It is very very hard even for a company with the marketing power of microsoft to unseat an established competitor that offers something that most people are happy with.

Sure google could be improved, but to switch you have to have something more than just a little bit better, you have to do to google what google did to altavista.
