That said: there are still many applications where tantalum 
capacitors are a better choice than ceramic - mostly audio-type 
stuff.  One of the major problems associated with ceramic capacitors 
in audio applications is microphonics.

But ceramic capacitors are my preferred choice for most of my SMPS stuff.
