I'll tak a stab at this question.  An instrumentation amp geneally
amplifies the differnece between it's inputs in the presence of a large
common mode signal. They may have an extremely low bandwith. 

An operational amplifier on the other hand is a general purpose building
block and is single ended.

A typical use for an IA is thermocouple signal conditioning or bridge
amplifier and data acquisition where ground loops are a problem.
