3D desktops are not at the responsiveness level of Windows or OS X despite improvements over the years. As a result, there is still a significant amount of Linux users using 2D desktops. For example, I'm using Gnome 3 fallback (i.e. classic mode) with xmonad. I know quite a few running AwesomeWM with no DE, and others using Ubuntu 2D. That being said, setting up xmonad or AwesomeWM requires a higher initial investment but you gain more control and efficiency in the long run. It's the same argument for using vim/emacs over notepad.
