Microsoft decided to let Windows XP live on for an additional 6 months (at least in Norway). The option to downgrade from Vista to XP was supposed to end on January 31st, but the date has now been moved to July 31st.
I predict that, come July, this will be postponed further – and that users will eventually be upgrading to Windows 7 and giving Vista a miss altogether. I also predict that nobody will bet against me on this.
UPDATE: John McCain’s campaign was just compared to Vista. When non-techies start using your product as a synonym for epic fail, you may have a problem.
