Cost of replacement and squealing noises were the two main factors putting me off, I understand you can switch to steel if you want to from ceramics, but don't you have to also change the master cylinder and a few other gibbins?
In any case, if ceramics aren't a concern for someone then fair play, go for it, personally I wanted to be able to change my own brakes and not break the bank in doing so, with 3 cars to run it seemed more prudent then ceramics for my own personal circumstance.
There are pros and cons to all specs based on opinions, some thing the B&O is overpriced and Bose is adequate (which it was in my S4) but personally I think its worth the difference, whereas the brakes weren't worth the difference to me.
