One of the many features available to most users is the weather screen:

By simply entering the zipcode or city and state, you can setup numerous locations which can be viewed by simply wiping the display to the left to show the next location. This will allow you to setup locations such as you where you live, where your loved ones live, and where you wish you lived and view the real time current weather conditions at those locations any time you choose. And you can touch the Yahoo icon to view the weather forecast for that location.
