If you don't know what linux is, you won't understand this.

I'm pretty sure that the definition of an OS is that it has to run without another OS under it, otherwise it's an emulator. And the last line is golden.

Ah... Hillarious. For those who don't know what Linux is, its a GPL-licensed piece of open-source software that replaces Windows or Mac OS X as your operating system. It has made significant progress recently, and is developed largely by volunteers. It is most notable for being free and open, although does not have the corporate backing and support you get with Windows. Certain distributions, or version of the software modified to actually be useful for the user, may have support (like Ubuntu), and others may have a premium version (like Mandriva). In general, it is debatable whether it can be successful on the desktop, however has become very much so on Netbooks and Android-based devices (like the Nexus One), which increasingly run Linux. As a bottom line, Linux currently is more for geeks and power users.

As for the message, I'm not sure how much this guy actually understand what Windows itself is. It doesn't "run" the computer, it just sends it instructions and receives replies.

Isn't linux an OS....just like windows?
LOL

Whoever wrote that is a complete fool. The Mac part I genuinly LOL'd at. Mac's have been making their own OS for longer than Microsoft. (And also been running Microsoft Office for longer than Windows...) As for the last sentence all I say is: maybe you should reexamine your assumptions...

This is what happens when people decide that Windows was the first OS ever of all time and kills every other computer.

This is what happens when people don't know anything about anything.
