Another advantage of a real PM is you can use it on the trainer in the winter or bad weather and get some solid interval numbers.

ibike, especially one that's not calibrated against anything else, is no better than an HRM. In many ways, i'd argue it's worse as you can't even download data in some of the cheapest versions available, which makes it no better than a $60 Timex watch you can buy on Amazon.
