As of this very moment, MacOS X 10.6 and Windows 7. Neither of them ship with a video editor of any kind out of the box. That’s right. Of the three operating systems, Ubuntu is the only one that ships with any video editor at all.
Huh? My iMac shipped with iMovie, and Windows ships with Windows Movie Maker.
update: whaddyaknow, windows 7 doesn't actually ship with the movie software, you have to download it (free) from http://download.live.com/moviemaker. Still.
