uses
Don't you use any applications? I find the dock to be a wonderful source of application management, among its other uses. I use it rather like I used to use the "Recent Applications" menu in os9. Just drag all the applications you frequently use into the dock, and there you go, instant access to any one you want. Unless of course you only use one application, which I wouldn't really understand.
Yes, I do know there is a recent items menu in X, but its so much easier to just clikc once down in the dock, rather than to open a pull-down menu, open the contents of the recent items, and then click the application you want... 🙂
