Discovered Ubuntu in 2008, but really switched to linux on dekstop in early 2012. At that time, I totally removed windows from my hard drive, and realized I could perfectly live without Micro$oft...The sensation was like being released from jail.
I'm a free man now ! Thanks to the people and the FOSS community.
And it's been 4 years that I administer an ubuntu server as home server (at home, behind optic fiber, in France ;o) Postfix, Apache2, Samba, FTP, Ejabberd, SQL, openerp, owncloud...etc learned a lot !
