I heard gates talking about it on CNN, or something not too long ago, the deal is, if I understand it correctly, it's a microsoft search toolbar built in so whatever you're doing- word, excell, etc- there's a toolbar where you can just pop something in and go. I don't think it will block the usage of google or yahoo, it just makes their search more in your face and available. I wouldn't sell any stocks yet, but I wouldn't invest into any search engines either until this is tested to see if it can hold water.
