Has anyone started using CREO 4?

Has anyone started using CREO 4 with built-in Keyshot rendering capabilities?

First impressions?
Has it helped your workflow in any way? Hindered it?
Any major pluses or minuses?
Tips or tricks to aid in working with it?

IT gave me an evaluation copy to test out, and I'm still trying to get the hang of it (I've only had very basic experience in Creo 2 and 3).
