I suspect a bit of a pack mentality happening somewhere, considering just how few people have experienced it, but also considering that those who tried it seem to feel they are quite OK and nowhere near as bad as "30"" actually sounds like.
Personally, I will reserve my judgement until I try the seat and decide for myself if it is OK or not. There are still other aspects of CE to consider, for instance, most importantly (for me) the empty middle seat.
