Yahoo shareholders should notice couple of things that i think is important to know:
1. "your hand-picked nominees to take control of Yahoo! for the express purpose of trying to force a sale of Yahoo! to a formerly interested buyer" --- if the new Icahn's board is only interested in selling the company then it could be dangerous as MS may not show any interest to buy yahoo or may offer low price, in either case it is not beneficial to sharholders.
2. "Following that meeting we also provided to Microsoft a list of key non-price deal terms that our board believed were critical items to be addressed in a deal to provide reasonable protections for our stockholders." --- i wish Yahoo explained what were the non-price deal terms, nevertheless it shows that they (yahoo) did due-diligence very well.
