Last year I installed a SSD in my laptop and the only OS I installed on it was Ubuntu 12.10 with Unity DE. I started out with 12.04 and have not used Windows since that release. The only thing I kept windows around for was Netflix but now I have a Nook, Asus Transformer Tablet, Bluray DVD player and a Roku box for that so I don't use or need Windows for anything any more. I am totally MS free.
I love Open Source Software.
