I have wired eTap on my road bike and it's so GD smooth. Adjustments with the software are so easy too - I was never too mechanically inclined though. They have wireless electronic shifting on top end road bikes and I can't help but think that security probably isn't top notch. Can you imagine, the last sprint of the tour de France and shifting everyone into a low gear - you'd likely pop the chain off and cause real hazards and (rightly) face charges.
