The world is flat. Those dang automobiles will never amount to anything. Who needs the internet. A PC will never have more than 64K of memory. Who needs integrated shifters/Index shifting? Aero is for wimps. etc. etc. etc. Cyclists are so often just blinded by tradition, it's almost comical. Until they get their tail waxed by the guy that figured out the next new thing.

I'm not sure about this, but didn't DI2 just dominate the winners of the TdF?

I think this has a huge amount of potential. Talking to those that actually use DI2 talk about how much they like it. My LBS owner tried it to stay current and you couldn't pay him to give it up now. He loves it. I think being able to shift under load on either front or rear is a huge deal, a game changer even - maybe even especially for those who aren't all that experienced. The micro adjusting of the front and rear is pretty cool. I'm thinking that a MTB group could be pretty interesting too - changing under load anyone?

This is probably where it all goes in the future. This is going to continue to get cheaper until it pretty much covers any bike that is tiagra on up at some point.
