Microsoft really wants people to get excited about Windows 7 so they’re showing people how to put on Windows 7 parties with a video, that already become famous for being incredibly lame. It’s so out-of-touch that it’s funny. For an even funnier take, see Mac fan Cabel Sasser’s take.
While, in all fairness, Linux users aren’t known for being party-animals either, Linux users do enjoy sharing information at a social gathering, and they don’t need Microsoft to tell them tell how to throw a party. Instead, they get together around the world at LUG (Linux User Group) meetings.
Once upon a time user-groups, people who just got together because of their shared passion for computers, were everywhere. As PCs became as common as refrigerators most of these groups died out. In the case of Linux, though, they live on.
