Microsoft have pushed back the release date for their next-generation operating system, Windows Vista, to January 2007. This could prove disastrous, considering that this move will move Windows Vista's release past the Christmas buying rush, meaning that Microsoft's sales may be hit. Also, PC manufacturers (OEMs) will not be able to sell the new PCs running Vista, so they may also be hit by this move as well. Interestingly, though, Microsoft are allowing some of the business versions of Windows Vista to be released to companies in November 2006.
UPDATE: Huw here. The Wall Street Journal is reporting that Microsoft is fiddling around with the Windows Division Management. Obviously Ballmer (Microsoft CEO) and Gates (you know who he is!) aren't happy with the Windows Divison performance, and are moving in Steve Sinofsky, formerly of the Office Division to lead Windows Development, presumably in the hope that he will instill some of the promptness and urgency shown by the Office teams in recent years when providing updates.
