My current whirlwind tour of operating systems has taken another turn - I dumped Ubuntu and installed Sabayon Linux. The Unity interface in Ubuntu was making me mental. It was just too cumbersome when working with more than one thing at a time - I need to readily switch between two or three things and it was too clunky for my liking, or perhaps I should say for my way of working. I'm taking a bit of a chance on Sabayon 9 - it's Gentoo-based, so I'm moving away from the Debian/Ubuntu/Mint universe. This version has Gnome 3 and so far the differences between that and Unity seem to be acceptable. So far so good - stayed tuned!
