Over recent weeks we are seeing more and more about how people within the 'bing' team are all talking about how 'we' are all trying to get along and live along side google... The reality seems to be very very different if you talk to the other microsoft divisions.. If you take all of Steve Balmers comments about wanting to 'kill google' and 'bing will take over' there seems to be a big change in the reality.. I suspect that its all part of the 'poor microsoft story' that's focused on making them out to be the poor underdog when in reality they are investing billions in taking peoples choice away by creating agreements with carriers etc to either include only bing or do other 'techniques' to try and artificially win search transactions and therefore advertising revenue.
I'm not saying that Google does not pay for people to use their search, there are agreements for revenue sharing etc the key is that googles services for the most part are soo good that people want to use them.. bing still has a long way to go despite being an improvement over 'live' search crap.
