"If somebody came to you and said you have a new competitor that has no price and has no cost structure you might stay up a night or two on that one."

--Microsoft head Steve Ballmer, taking about the dangers of open source software in a recent a talk at Stanford as quoted in Wired News.

The NY Times points this out is a relevant statement at a time when new ComScore data that shows Google has overtaken Microsoft as the most visited network of web sites, but I like this Ballmer quote from the same talk better in that regard:

"Google built one very good business. They only have one thing they do. Everything else is sort of cute. We do a lot of things that are cute, too."
