"Not nearly as good as WeatherBug"
Not many, other than it actually works. WeatherBug suddenly does not (thanks to the latest Mac OsX update), which is why I downloaded this one.
Crappy doppler radar pic, requiring user to click through to internet connection to weather Underground to view local doppler radar info, the most useful feature of any dashboard weather app. If WeatherBug worked, I'd dump this right now. However, this is all that's out there.
