Okay okay... so for all those Windows users with Mac jealousy, now you can have the fancy icon bar with animations too. Check out Rocket Dock. It's free, and it works well.
So far, so good. My only complaint is that when a window is open, it appears only on the Windows status bar, not the Rocket Dock. It would be nice for it to always be on the dock. I'm not a Mac user, so I don't know if that's the expected behavior of the dock?
Next up, Switcher:
Switcher is another spin on the whole "Alt-Tab" window switching scheme. Vista introduced the 3-D Window "carousel" by clicking "Windows Key+Tab". Now, you can "Alt+~" to "Switcher". Switcher will "auto-arrange" all of your open Windows to large thumbnails that fill up the entire screen so you can see all of them at once and then choose one.
