Vin - Without getting into a debate, my coworker who has a Galaxy Nexus regrets buying it. Constantly reboots and crashes or does something retarded on just about every ROM he tries, even running stock. So yes, HR could be saying something slightly different, but still negative.
I've seen a noticeable jump in battery life with 5.1 myself. Love my iPhone.
