I'm an OS (Operating System) junkie. This year, I've test driven more than a dozen OS's, just for fun. The one pictured here is Linux Kubuntu. I've tried the latest Linux Ubuntu, too -- and think it is daft. Fortunately it has a "retro" switch, to retrieve the old look and feel. It certainly is fast. OBSERVATION: Various versions of Linux top my list of favourite OS's. I look first at the file system and the management of software / drivers. These, for me, are the litmus tests of Linux distributions. Windows just annoys me.
