Comment on WeatherDock

The only reliable menubar weather product I've found. I've used a couple of others, and they've always choked at some point, but this one never fails. And the features are just great: it can speak the weather on a schedule if you desire, manage many locations... the list goes on. I can't believe it's free, honestly.

And about the icon, you can easily customize it so that when running the icon shows current conditions, temperature, humidity, wind, whatever.
