Good for you, i used Mac for a long time, then I had to use Windows for work which extinguished all joy... Then finally, I jumped into Linux full time and I've been so happy ever since. Sometimes I have to use Windows so I run that in a VM, but with enough RAM the world is your oyster. I am just a vanilla Debian user, and it's great. I've been enjoying KDE vs GNOME quite a bit. Welcome and enjoy!
