I'm trying the Gnome 3 desktop environment for Debian 8 and it really isn't that bad, reminds me of Windows 8/8.1. I'm using MATE in FreeBSD which is a for of Gnome 2. And starting with Vista Windows uses DWM I think or that might be like Xorg. They use Aero. Windows also uses the Windows bootloader and Linux GRUB. I really would like to be able to install the Windows desktop environment just like another environment like KDE or Gnome. I've forked the Budgie Desktop environment and made my own called Blueberry for Linux and Gnome Shell. I've also forked the Lumina desktop for BSD which is a low level C++ desktop environment. Fairly new.
