Hermes, I and my wife are definitely early adopters. Sometimes for the better, sometimes not. For example, we took delivery of a Gen I Prius in December 2001. A few weeks ago, we took delivery of a 2013 Ford Focus Electric (and sold our Gen II Prius). Given all of my accumulated bike stuff (including some nicer wheels), I've been watching the (non?) development of pedal power meters. I bought the Garmin Edge 305 within a month of its release and I've been very happy with my Garmin computers since -- despite what some people say about Garmin and the computers on the web. Besides, someone has to be first, right?
The best way for me to do crank-based power meters is to spend a lot more money than I think I can swing right now given that my three main bikes have incompatible BBs. Of course I've not mentioned my track bike in all of this discourse and that's the bike that I spend more training hours on other than the Serotta.
Speaking of the track, if it's Thursday then it must be time for Roger's Session.
