One of the publications I find very useful and always relevant is Knowledge@Wharton, produced by the Wharton School at the University of Pennsylvania. Check out this timely article, Microsoft’s Multiple Challenges: Is its Size a Benefit or a Burden?

Excerpt: “Microsoft announces that it will spend about $2 billion to fend off rivals such as Google and thwart Sony’s video game ambitions, and the company loses more than $30 billion in market capitalization in a day. Fair trade or overreaction?” My favorite quote? Wharton finance professor Andrew Metrick’s comment that “$2 billion to Microsoft is like a pimple on an elephant.”

Certainly true, but the investment demonstrates the range of rivals Microsoft faces in retaining its “titan” status for the long-term.
