Learn about basic OS X applications I have been a Windows user and have recently started using OS X (I have Snow Leopard on my machine).

I wanted to learn about the basic applications in OS X (e.g. Terminal) and other commonly or some important utilities used in OS X. I know a lot of important apps come bundled or pre-installed with OS X, but I am not aware of a lot of them.

Could someone please point me as to where I can learn about such apps and what are the important apps which I should know about?
The Mac 101 on Apple website seems like a good place to start.

And of course, Ask Different.
