I've gotten used to the MacOS style of navigation. And I like the concept of having your 'hot' programs 'docked' on your screen - some what like the quicklaunch you get with Windows. Well, not really.
So RocketDock gives you the dock-like features you'd get in the MacOS. It takes quite a bit of getting used to, but the fancy features that RocketDock comes with makes it worth the install. RocketDock also helps give you the ability to customize pretty heavily, so that's pretty sick.
Check it out, yo.
PS: Have you checked out "imeem"?
