"At the end of the day, we're in it for business reasons. I exist for business reasons. I do not exist as a PR stunt or as sort of an olive branch." --Bill Hilf, Microsoft director of platform technology strategy, who heads the company's Linux and Open Source Software Lab, which studies Linux and open source as both a threat and as a platform with which Windows has to interoperate. Hilf thinks of himself as the non-Microsoft person at Microsoft, and prior to joining the Windows empire worked at IBM devising a Linux technical strategy. Ina Fried's story, "At Microsoft, the yin and yang of Linux," has some other good soundbytes.
