Favorite Mac Applications

[sanket-soft]

So, I have been using Mac now for about 2 years, and I am still finding new applications all the time to make my experience even better. So, I am personally interested in seeing what other Mac users here use and love. I personally love all of the iLife applications.
So what are your favorite applications ?
