Buying Turbo - PCCB?

I own both a 996C4S with steelies and a 996TT with GenII PCCB. The steel brakes are great, but generate a lot of dust. Like a lot of other posters mentioned, the PCCBs can start squealing, which is annoying as hell. I haven't determined the right course of corrective action yet, since there appear to be a number of solutions mentioned with varying levels of success.
The other negatives on the PCCB is that you have to micromanage anyone working on your car requiring removal of the wheels. It is important that they use a special wheel removal tool, because the edges of the ceramic rotors can get chipped if they come into contact with the wheel when mounting/dismounting. I have a couple of chips in the rotor. Porsche dealer tells me it is normal and fine. Per a Porsche TSB, it isn't, but I'm living with it.
One thing that is never mentioned is the impact the PCCB has on unsprung mass. My Turbo's steering is much more communicative. It is supposed to ride better too - hard to say since I have the X73 suspension on the Turbo and the ROW MO30 on my C4S.
And yes, you can replace the pads and rotors with steelies.

The PCCB rotors will last forever if you don't track your car. Agreed you have to be very careful with them when changing tires.. And a pad change on just the fronts after 57k miles works for me...
I love mine but if I was in the market for a turbo it wouldn't be a deal breaker for me either... The steel brakes are awesome as well..
The only time mine (PCCB's) have ever squeaked is when the wheels were quite dirty. After a wash the squeak always went away.

Gen II rotors are lot better than the Gen I and Porsche has now revised their take on the chipped edges I will see if I can find that TSB where Porsche tells you the measurements of the chipped edges that are safe to drive.

I find them to be most delightful! They are a major improvement as I've stepped up to a 2012 Turbo S with PCCBs after 9 years or so in Porsche's with the intermediate grade red caliper brakes.

That was one of the must have items for me when I was shopping for my 997 TT
Yes they are bitch to take care of but the initial brake bite, almost no brake dust and the weight bias were enough to convince me to get them.
In all honesty though, If it was my daily driver, I would be very cautious who touches my wheels and the brakes as they are quite easy to get damage.
