Well tonight I thought about something I saw on a guest speakers computer this week and it really interested me. So I decided to check into it. Windows docks really have come a ways since a few years ago when I last tried them.
I found that there are 2 major docks that are in use and are active. Rocket dock and Object dock. I tried out the free version of Object Dock though and Rocket Dock is free.
They both have some key advantages from what I have noticed in a couple minutes of use. Rocket Dock to me is simpler and it gives you the option to re open an applications window based off of the apps icon vs having minimized images for each window in Object Dock. However, Object Dock is good for when you maximize windows as it disappears automatically like the desktop I guess, where on Rocket Dock you can have auto hide like the windows task bar but that is not the same having to mouse around down there to get it back up. I think it is just personal preference as to the one you choose but personally I like Rocket Dock more.

The Rocket Dock site is a little slow so here is a link to it. It is 6.2MB.
It works on 2000/XP/Vista and they say that they don’t support XP 64bit or Vista 64. However, it is running on my Vista HP 64bit just fine.
