You have all heard the jokes that the end of the Mayan calender on December 21st 2012 might bring about "the end of the world" in some type of cataclysmic event. Regardless of whether or not this is necessarily true, there have been more than a few technology releases/announcements in the past couple years that many of us thought would never happen.
8. Starcraft 2 releases (and runs on Linux!). This is one many gamers have been waiting on for some time. After Starcraft Ghost turned into vaporware I think some of us where wondering if Blizzard was ever going to release anything other than WoW expansions ever again. Starcraft 2 is finally here and it was worth the wait, easily one of the best RTSes I have ever played.
7. Microsoft releases a decent desktop operating system.
