This is not exactly hot news, just a quick reminder to count the last days: A table in this article mentions MS-DOS (as well as Windows 3.x, Windows 95 and NT 3.5x) reach their "End of Life" (as defined by Microsoft) on December 31, 2002. Come on, even if you loathed them, they were good for jokes at least!

Source: Slashdot.org. I would like to mention, DOS was a good operating system although lacking some features.
