TechWeb reports that Bill Gates' CES presentation was
interrupted by a BSoD. The only problem with this article is that the presentation was apparently on an Xbox. Xboxes don't BSoD, they "GSoD"--the error screen is green, not blue. I don't know if the unnamed reporter got the details of the presentation wrong or is reporting second-hand news, but something is not right about this.
Six years ago, at another tech conference, a Windows 98 demontration also conducted by Gates
crashed with a BSoD. The linked article includes a QuickTime clip of the crashed demo; note the audience hooting when it happens.
Edit to add: There were at least
three gaffes during the Conan O'Brien/Bill Gates keynote, one of which was during an Xbox demo. The BSoD seems to have occured during a Nikon camera demo.
