You can also use Growl in conjunction with mail rules and scripts to notify you in a variety of ways when you receive very specific emails you may be waiting for. I want to know time is passing, but I don't want to constantly be looking at the clock, and Growl provided an excellent way to do that. I use growl in conjunction with a chime app to notify me of time passing on my home computer without have the clock visible too me. If you IM at all and you don't like blinky, flashy things in the dock but you need visual notification from the computer, you can set that up rather nicely with growl. I'm sure you can do this at the terminal with BSD commands, but growl opens up some fun and fascinating possibilities. I don't know how to explain it, but it's on my list of "life changing technologies" for me because it is so amazingly flexible in how you can set up notifications for events.
