mavic tried and failed with both the Zap and Mektronic systems.
Mektronic was far better than Zap but still had problems. I know
alot of tandem riders who like them due to eliminating the long shift
cables.
Campy's design reportedly corrects/avoids the problems that plagued
the mavic sytems.
For a pro you have silent servo driven shifts, and not too much of a
weight penalty. precise shifting due to servo?
Would I personally buy it? don't think so, I'm quite happy with
my friction shifters and one ergo setup.
Will the pro's use it? Yup, I believe that Once used it 2 years ago,
and there will always be those teams that on the bleeding edge.
OCP members (those worth their membership cards) already have
downpayments on the system.

edit: I believe it's a wireless system for the most part, no cables or wires
from brifters to derailleurs). Individually coded to avoid interference.
Can you imagine if a pro initiated a shift and half the peloton shifted?
bloody murder would ensue.
