Yeah I see your points on this...
I like the old "write it on the kneeboard" style too, is a lot quicker than dialling in a load of information on this thing, but I have been shocked at the amount of people who don't really use the ATIS information as it is intended.... They copy it fine and relay the Phonetic letter back to ATC and go on their way...
This little gizmo might actually drum home why we are given this information in the first place as they actually have a visual representing what is happening in the real world.... Granted though, a simple diagram would suffice just as well to show wind/runway direction...
Hmm... don't think I'll be buying one too soon.
Fair play to the designer though, I'm sure he'll sell a few along the way.
