Alright... Like I said before you can have different things up on each desktop (Some people might not like to have lots of windows on their taskbar.) You can organize files and programs on each separate desktop, one for gaming, one for internet, one for work. (Less clutter on each desktop, each one is file specific. I know you can use folders to do this, but some people may be super lazy and not feel like opening a folder.)
I'm done arguing, you can believe what you want. I don't want to start a war.
Let this topic die.
