That is a very interesting question that I never thought to ask myself.

With Oracle’s stock up so much in that period of time, it seems that investors in the stock market think that Larry and Oracle are doing something right. So, what would Larry buy if he was running Microsoft?
Here is an article by Randall Stross in the New York Times that is suggests what Larry might do… http://www.nytimes.com/2008/02/24/business/24digi.html. Definitely worth a read, whether or not you think Microsoft can learn from Larry.
