The 60 second interval is not a show stopper for me. I am very patient, so I am still waiting to see how the Acurite Atlas Elite pans out before I buy. But if the price of the Elite is too high or the user reviews disappointing, I will probably go with the WS-2902 Osprey. I do wish it had an aspirator fan option though.
The biggest advantage of the ObserverIP is really not its ability to doe the rapid fire feeds, but rather that it can feed a Meteobridge (Ambient Weather WeatherBridge) which in turn can feed so many different weather networks that I have lost count. ObserverIP IS limited to the networks that AW ordains. Meteobridge is actually firmware that you download into a very inexpensive router turning it into a dedicated weather broadcasting platform. The WeatherBridge is simply a turnkey implementation for those that are uncomfortable with flashing firmware. Either one gives you the same results just the former is WAY less expensive!
