Have you seen the wattage list discussion from over the summer? Topica is down right now, so I can't give you a direct link, but if you google "wattage topica ibike" you should be able to find the thread in the archives.
Two more weeks with the ibike and I'm still happy. It has some quirks, the biggest being the data dropouts and the rarer high wattage numbers. I ran some calculations on my ride files in excel, and it looks like I lose data usuallly between 2 and 4% of the time, with the occasional exception, like one ride that had a lot of brand new chip seal, and another crit that had a section of cracked road, both of which were about 9%. A couple other quirks I haven't seen mentioned before: the windspeed appears to read high on my unit, claiming a higher wind speed than ground speed even when I've clearly got a tailwind. Also, during high accelerations, the hill slope number tends to climb artificially. Neither of these anomalies appear to affect power readings, however. I suspect that the power algorithm is based off of stagnation pressure in the anemometer and combined gravity+acceleration forces in the accelerometer.
One last note. I wrote the ibike people with some suggestions on how to make the unit better for serious power training, and they told me they were waiting until interbike to announce some improvements that would "delight" me. I've got my eyes peeled ...
