The WLL supports all the current and popular weather applications; Cumulus MX, Meteobridge, Weather-Display, the WeeWX. But I can see if someone is still running some of the older applications to then still keep their console and logger around. For example to continue to run Cumulus 1, Weatherlink for PC, VWS....etc. Also required for WiFiLogger and MB NANO users (unless they have an Envoy).
What I'm saying is that it isn't solely about the visual display itself in many circumstances.
