Re: battery life, one day last week I forgot to charge my phone overnight, and the battery ended up lasting around 40 hours with light to moderate use (texting throughout the day, a phone call, I think a YouTube video, checking Facebook--stuff like that). I have Gmail and Facebook sync on; I constantly have the Google Voice, Plug-in Launcher, Sipdroid, and Light Flow services running; and I put my phone in airplane mode with wi-fi on at night (wi-fi remains ON the whole time--still checks for push notifications and Sipdroid calls when the phone's asleep). I'm running 20110531.
If you guys are having serious issues with battery, my guess is that either you live in an area with very poor signal or tower-hopping, or an app is the culprit. AospCM battery life is a little worse than stock, but not enough to call it "awful," "horrible," "abysmal," or the other adjectives I've heard.
