Nah, NFPs have Te as a function, whereas NFJs have Ti as a function.
Not necessarily true.
I have a well-developed Ti (31% use) and virtually no use of Te (13%), so it depends on the individual NFP and their functions.
EDIT: PinkPiranha's TI-85 is PRE-HISTORIC. Anyone who's anyone('s friend of several engineer majors) can tell you that the hot and happening graphing calculator of today is the Titanium TI-89. Who doesn't know that?
... er um...
Don't worry. My dork is going back inside the cave now.
