You don't have to make the argument for me on this one. I've already ordered the hub a week ago (just waiting on CycleOps, but they're just getting back from Interbike). I've been training using Training Peaks for years and while it works fine, I'm finding my HR to be much more unreliable as a benchmark as I've gotten older. I plan on using the powertap pretty extensively on the rollers and the trainer this winter because for some reason, data keeps me motivated when it's dark and snowy out.
