And that doesn't include the several large field sites in the U.S. (Charlotte NC, Irving TX, Fargo ND, Silicon Valley, New York, Boston) and elsewhere. I've worked for Microsoft for over a decade, both in the field and on campus, and while some groups are like a "start-up" in the sense that they're brand new, everyone knows they work for a huge company. For most of us, that's why we're here; we get to do really neat things but with the relative security of being at a big employer.
