Here are a few things you should look at at least once

1. Firefox 2.0, the web can be a dangerous place. Using Firefox as your web browser can help to keep you safe from the most common attack vectors.

2. Google's Gmail, most people have a use for a web based e-mail account. I've got one from most of them and Gmail is by far my favorite.

3. Picassa, I have numerous digital photo's, and a need to keep them organized. Picassa is what I turn to to make this task easy.

4. Google Talk, if you have a need to instant message friends and acquaintances you should try to get them hooked up with Google Talk. This may be a tough sell, people tend to be pretty firmly entrenched in whatever their current IM client is.
