I don't know that there's any advantage to the cabled version except lower cost...
I've got the wireless, but with the standard wired anemometer. I'm now strongly considering buying the xmitter for the anemometer so I can place the ISS unit more freely (rain accuracy issues). Sure, I could extend the wire, but it's so limiting...
With the wired, you have to consider where/how it will enter the house, which will fix the position of the console, and therefore fix the position of your computer (assuming you'll download your data and post it...).
I guess you could get around that by putting the console in retransmit mode, and buying a Weather Envoy to receive the data, and hook that up to a computer in another part of the house... But then, you may as well go wireless from the start...
Just one opinion...
