Please post results. I'm thinking of getting one and wonder how well it will interface with the Mac. Are you using WeatherSnoop?
I've had the new Vue running for a couple of days and I like it. I am having no issues with the USB connectivity like I was having with the WMR100. I also like the compact sensor installation. I think the console is also much better then the WMR100 console.
The only problem I had was with the WeatherLink software. Initially it would start up and display an error about being able to find a certain file, which was clearly installed in the WeatherLink directory. I was unable to do the initial Vue configuration because the WeatherLink software would not run. A search of the Davis site said I needed to set the WeatherLink.app to run in the 32 bit mode instead of in the 64 bit mode. Once I changed to the 32 bit mode, it worked fine and I was able to do the initial configuration and get it talking to WD.
That was the only issue I've had with the Vue and I'm glad I got it to replace my WMR100.
I think the compact sensor installation would be a good fit for someone who travels. The sensors could be installed on a nice tripod and set it up in a good location (like the roof of a camper?).
The lack of Solar and UV sensors didn't really bother me since the WMR100 didn't have them either.
I'm quite satisfied with the Vue and wish I had got it sooner.
