Jim,
We work with CS5 and as Todd said the Vibrance effect is in AE, I think its a great effect and often add a small amount in an adjustment layer.
My workstation is a 12 core mac pro with 32GB RAM but only stock HDDs. I do find dynamic link to clunky, although great integration. Many projects I work on are in and out so quick there is no time for back and forth with AE.
Thanks for the comments guys ^_^
