I switched from Windows XP to Ubuntu 7.04 and i still like Gnome 2, but after half a year i switched to Mac. For private things i still use OS X since i don’t had the time yet to learn darktable (as Lightroom replacement), but a switch to Linux is planned for years. At work i use elementsry OS since the Loki release and i’m really happy! This distro is exactly what i need (as a Mac user who wants a system that just work and is beautiful). I also contribute when i can. That is what i like the most about free software!
