Windows version: Stardock
One of our favorite features of OS X is the dock, a customizable taskbar you can anchor to any edge of the screen, and even set it to duck out of sight when not in use. This gives you a good chunk of extra screen real estate, otherwise taken up in Windows XP by that horrible excuse for a taskbar.
Stardock ObjectBar brings some of that dock goodness to Windows, giving you easy access to programs, folders and common processes. All this is done with succinct icons and spiffy animations rather than clunky text. ObjectDock is endlessly customisable, and users can add their own "docklets".
For an extra US$19.95 (S$28.80), you can upgrade to ObjectDock Plus and get multiple and tabbed docks.
