I really didn't mean this to be adversarial. And honestly I think I've given the Ibike more credit than a lot of people who dismiss it completely out of hand.
All that said, I think you're seeing a broad consensus in this thread, and other power meter threads, that the Ibike just isn't where you want to spend you money, particularly now that there's a relatively affordable PT option.
Note that even many of the people that post relatively favorable reviews of the Ibike for some reason are no longer using it.
So you can take the accumulated experience of people who have been trianing with power for a number of years, or you can spend the money that would otherwise buy you a nice powertap and experiment for yourself.
