Users can select one of two themes, white on black or blue on light blue, as well as which photo service (TwitPic, TwitGoo, YFrog or Img.ly) to use and what kind of retweet style they prefer. A "Twitter Trends" view allows you to see what the top topics are on Twitter, with explanations drawn from to cut through the noise and tell you what everyone is really tweeting about.

A $2.99 upgrade offers a location-based "Nearby" stream, as well as the ability to read and add to Twitter lists.

Keep on top of the weather with this slick little app. AccuWeather presents just the information you need in a clear and attractive way, plus a few bells and whistles.

The main page gives the current temperature, wind speed, and humidity based on either your ZIP code or GPS coordinates, along with a 5-day forecast. (There are several other free weather apps available for the webOS platform, but I find that AccuWeather provides the most useful information right on the home screen.)
