Fairly nice Weather application.
I would like to see it extended with some more weather data alike: http://www.intellicast.com/Local/Weather.aspx?location=USNJ0315
"Current Conditions" - Wind Chill - Heat Index - Dew Point - Humidity - Pressure - Ceiling - Visibility - Wind - Direction - Gusts
I am not sure if this data currently is available, but has to be selected in setup somewhere (could not find it). This added data would make the application really useful for Aviation.

Before the recent update I would have rated this a 4 or 5, but now it's unable to update the weather at all. If I uninstall and reinstall it will get the weather update, but will fail after that. It's too bad, there aren't any other functional weather apps for the N900.
