*facepalm* Skynet is the main antagonist in the Terminator franchise, is a fictional artificial intelligence system which becomes self-aware and decides to terminate humanity, its creators. Skynet is rarely seen onscreen, with its actions often performed via robots, cyborgs (usually a Terminator), and other computer systems.
I wont vote, for a single reason: Windows: User-Friendly more than both linux or Mac's O.S. It also takes a huge piece of pie at the leaderboards of the O.S.'s used by people around the globe. Linux: Coder-Friendly, also faster than windows because it takes less pc resources, also, it has a more "basic" interface, that helps on making it faster Mac O.S.: Best (in my opinion) interface, it's pretty well designed and it has 'class' also, it's designer-friendly, because has less errors and Mac's are made by top quality matterials
Ubuntu 11.10 is spectacular. It runs on the Linux 3.2 kernel with a snazzy Unity interface. I run it on all my boxes with a Win 7 dual boot on a couple boxes.
So you do believe on whole Skynet story? EDIT: I have invented something against Skynet: Water. If you don't get the joke /kill
