After a bit of hunting, I found some recommendations and settled upon RocketDock from Punk Labs. At home I have a Gateway computer running Windows Vista business, and I wanted to add a Dock. I suppose that people who don't know any better might think that this is something you can only get from Apple, but as it turns out there are docks for Linux and Windows. You bring a running program to the front, or launch a program by hovering over the dock with your mouse, and clicking on the icon. Docks also can be configured to display running programs that have been minimized in a mini window. Docks also can run small programs or docklets that can do things like display a clock or show you the weather. The Dock is sort of an always there menu with big icons that spawn your most frequently used programs.
One of the distinctive features of Apple computers is a piece of software called ' The Dock'.
