Now, you've said you're not interested in sprinting, so this probably isn't an issue at all.
As far as gadgets go, the iBike is much more impressive than any other power meter. It attracts me as well for this reason, so I just turn that into a yearning for a handlebar wind tunnel...
I briefly reviewed the data files posted on iBikes website; where data from iBike, Quarq and PT were overlaid each other. It does appear that iBike produces readings that differ from PT and Quarq for very short intervals (~5 sec), but there doesn't seem to be any problem for longer efforts. 5" power is not super important to me, but 60" power is (I am a big fan of the 1K attack to the finish during our fast group rides; I think it was you who was a big proponent of that in the racing forums so I have been trying to incorporate that into my training) and I don't see a problem based on my brief review.
I will analyze the data further this weekend to see if anything else jumps out.
