Microsoft yahoo deal again

Its back again yahoo-microsoft deal, there is a news like some company which has 1.5 percent of yahoo stock asked yahoo to make a deal with microsoft. Actually Ivory investment management LP is a company which holds 21.4 million shares of yahoo. They said like they feel like it is an maximization oppurtunity.
I think if this deal works out , it is a good oppurtunity to microsoft to compete the playing field of google.
"Under the Ivory proposal, Microsoft would own and operate the combined search platform, with Yahoo becoming an affiliate that retains 80 percent of the revenue generated through searches on its own site," Ivory said.
At present google owns 70 % of the market where as yahoo has 20 % and microsoft has 10%
But what ever we need to look how this deal works out and what stratagies that microsoft would take on.
