Here is something I like..
 

I agree it is hard to say alot about a person in one session using PT. Here are the things I like.

A) I can review my hands nightly and see if I fucked up bigtime somewhere.
B) I like it in conjunction with Gametime+ to give me an idea of how loose a table is in general. You could open 4-5 tables, and then pick the loosest or tightest one depending what style you play better against. I usually notice a correspondance between VP$IP > 30-40 and me winning alot. Loose fishies, lots of them, usually pays.
C) It keeps track of my favorite fishies. I can do reports on who I have made the most from.

I do not think you are a moron if you do not use it, but it can help, especially if you build up a significant hand history file against people.
