Compiz Fusion is the best thing that happened to Linux desktop user experience yet. In the world of Linux bashers who argue that Linux is not quite ready for home users; compiz is one of the few things that really set Linux apart from other OS with major market share. It can give you good brownie points when you are trying to compare desktop effects with non-linux user friends, and it is truly exclusive to Linux OS. However, as it is with most other fancy desktop user interface (Aero for Vista, Aqua for OS X), the excitement quickly wears off after the first week or so; and those nifty little effects are not so awesome anymore.
