Well, I've never been penetrated by Windows...
Heh...hehehe...

Because Windows is a pretty lousy operating system compared to Linux.

Linux is more stable and efficient, much nicer and faster to develop in and for, doesn't get congested over time in the way that Windows does, and is far more secure than Windows will ever be.

On top of that, it's a lot faster to type things into a terminal then it is having to find it in a, with Windows 8 even more, convoluted graphical user interface. In addition, terminals give far more flexibility and feedback to the user than a GUI ever will. And yeah, I know Windows has CMD, but let's be honest - CMD is a horrible command line.

Linux is also far more customization than Windows is, without needing to install extra software. You can download and use any window manager you want, ranging from extremely lightweight to fully featured, tailoring the operating system interface exactly to your needs. Furthermore, the update system in Linux is faster and more user friendly than the one in Windows, and you never have to worry about backwards compatibility - what works on one version of Linux works on most others. There are some small details, such as file locations which may be different, but those are just small changes.

Finally, SSH and version control is an excellent reason to use Linux over Windows, especially if you're a developer. And Linux is free.

Having used Linux for 3 years, I can safely say that, given compatibility, I would take it over Windows in a heartbeat, and move over to it as the only operating system on my computer if I were able to play my games on it.

I mean, even small things, like alt-tab to move to a different window just works far better on Linux. If I've got multiple google chrome windows, and multiple notepad windows open, I can use alt+` to switch between chrome windows if that's the one I'm currently viewing, and alt+tab to switch from chrome to notepad and back. That way, I don't have to go through a billion different options of notepad, word, vlc, skype, msn, etc. as I try to find the chrome window that I'm looking for.

And multiple desktops, in which I'm able to press CTRL+ALT+Right Arrow in order to move to a different desktop window, completely abstracted away from the first. If I want, I can move windows from one to another, but it's a clean environment which I can use to improve my productivity. Right now I'm using Windows, and as you can see, instead of being productive I'm posting stuff on N4G lol.
