The real problem with the Ibike is the price. As everyone has indicated there are calibration hassles, and some accuracy issues with the Ibike, although, there are a number of reports that the I BIke Generation III is not that bad.
That said, when you look at price, there's little reason not to get the $659 Powertap complete with wheel.
The ISport is not a serious tool for training given the lack of a computer download.
The IPro runs $429 wired, and $698 wireless.
The one thing that would be cool would be a IAero paired with a SRM, Quarq or PT, so you get the "virtual wind tunnel"
but again the problem is price, $798 for a head unit, when you can get a Garmin 500 for $249.
Make the ISport $99, the IPro wireless $199, and the IAero, $299, and they might have a market.
At current pricing, the Ibike just isn't a good value proposition.
