I'll give the same answer I give when comparing 200x hull and sail designs to 198x models: The sea hasn't changed.
As a former dinghy sailor I still rely on the Windex.
Shroud feathers, Elvstrom ticklers, loose sail threads and even ear hairs can all help with interpreting the wind, so it's never bad to have lots of information.
It seems of the big three (speed/depth/wind) to be the one most often on the fritz.
