Docks became popular when Mac began using them in their operating system. But these days docks are available on all platforms. So which ones should you avoid and which ones should you use?

1. Simdock

It’s in the official Ubuntu 8.04 repository, but don’t ask me why. The screen shot says it all.

Now, which ones should you try?

1. AWN
Short for Avant Window Navigator, AWN is one of the best docks availabe this day. It offers great applets, you can download themes from the internet, it has a flat and 3d look (look here for the curved look). You can set all kind of effects for the icons.
