OS

Originally stands for "operating system", this backronym stands for the Indonesian term "otak sistemik" (meaning "systemic brain"). The intended meaning of this backronym akcually refers to the Indonesian term "kerangka berpikir" (meaning "framework of thinking").

Bro stop, I’m not talking about an OS — I’m talking about my "otak sistemik" setup.

OS X 

Came before Vista.

Irritating Fanboys and silly marketing campaigns (albeit now Microsoft have emulated them too- see the pattern here?) cloud its actual benefits, but its largely used for its creative capabilities. And when I say, "capabilities" I mean Logic and Final Cut work only on OS X, Industry-standard programs.

A 'true' user of OS X is generally quite irritated and bemused by fanboys and marketing campaigns and couldn't careless what OS you use or how much money he/she paid for it, because it works for them and they are rather pleased no one bothers making Virus' for their OS.

Apple Fanboy: "lolololol OS X is sooo cooool and I liek it lots I can make coooool beats and moovies lol and adverts!!11!!"

Microsoft Fanboy: "yeeeeah lololol youre sooo ghey I can play videogames lolo and DOS websites, gg n00b"

"True OS X user" : "So I've got a job and get laid regularly. Both of you Sod off"
