Here's a first look at EndNote X from TUAW. Among the features added is drag-and-drop pdf management. I am using Bookends, and the ability to use it to keep track of my downloaded/etext articles is essential. I do wish that it was a bit more tailored towards this, but then there are a few quirks with Bookends that bug me. Still, Endnote has long passed the bloatware threshhold and I can not imagine going back to it.
