Zune 2K Day
Playfully nicknamed “Zune 2K” day after Y2K day, owners of Microsoft Zune devices began reporting that their devices had malfunctioned and refused to boot up. The problem turned out to be a “a bug in the internal clock driver related to the way the device handles a leap year,” as described by Microsoft. The problem would fix itself on Jan 1, 2009 if users let the battery run down and then reset the device on that day. Certainly, the publicity from this gaffe couldn’t have helped the perception of the Zune in the marketplace, as by this time Apple’s iPhone had started its dominant rise. Microsoft said it would issue a bugfix for the device so that this problem wouldn’t re-occur in 2012, but by that time, Microsoft had already killed the Zune line of devices so I’m not sure if the problem was ever actually fixed.
