Yes 8-).

CoreText is designed to be the base text layout engine for out platform.
And it's based on somewhat different graphics model from the Cocoa 
Text System.

CT is mostly relying on the CG graphics state for specifying rendering 
attributes whereas the Text System is taking more markup attribute 
kind of approach.
So, even though some of the text attributes are toll-free bridged, 
text attributes recognized by CF is subset of the Text System and 
possibly stay that way.

In other words, if you need to use all text attributes supported by 
the Text System, you should stay with the Text System.

You should have to go down to CT for very limited reasons (i.e. 
writing your own text engine).
