not to beat a dead horse, but has everyone remembered to disable NFC? i remember I did this when I first got the phone after hearing that it was a battery drain, and it seemed like it helped me. This is like my 6th day with my Nexus, so I still have to condition the battery a little more I think. So far, my battery life is ridiculously good. I had the Epic before and it was nowhere near close to what this is getting; it's actually my favorite aspect of the phone (outside of everything else great about it).
i would also suggest turning off push in Email (not Gmail). doing this helped my battery life, but even with it on I can make it a full day easily (with pretty heavy usage). i do have wifi here at work though.
