If you feel so bad that you don’t have Apple Mac Dock for your Windows PC, then Stardock’s ObjectDock is your answer :)
Its a good add-on for Vista. There is a free as well as Plus! (which is shareware) version. The ObjectDock Plus has many features than the free one and the best one is the Flyout Menus which is similar to Apple’s Stack
I was using the free version for long time and I bought the ObjectDock Plus today and here is my Flyout Menu
The animations in the Flyout Menu is great and doesn’t eat much memory too. Thats one of the reason I like ObjectDock most. They don’t eat memory more and you can configure the way ObjectDock want to use the memory
Most of the things what you see is customizable
Another application I like from Stardock is LogonStudioVista which allows to customize the Vista logon screen. There is also an XP version available. It has even caught the attention of Windows Vista team!
