think like this,
for 8 billion they could have got a
good 20 % stake in facebook, facebook needs cash... they get cash to buy skype and
microsoft get facebook that has skype and a profitable
business,
for 8 billion they get more than 600 million skype and 600 million facebook customers and a more dominant online presence that is kicking google off its only source of revenue, facebook now is more popular among advertisers than google....
