I love this phone. After owning the OG Droid for two years and the Nexus for two weeks, this is the best phone I've owned. It has been absolutely flawless. No crappy camera like the Nexus. No poor battery life like the Nexus. No reboots like the Nexus. No signal/data drops like the Nexus. I bought the extended battery for the Rezound and it lasts me 20+ hours with heavy use (for me) and screen brightness turned up. I no longer have to worry about having to keep my brightness to a minimum to make my battery last. I can unplug it at 7am, go to bed at midnight and still have 40% left, which from experience will last me until noon the next day.
This phone is perfect for me in every way. I like the build quality and the size/weight with the extended battery. The navigation dock is awesome because it fits with the extended battery too, even with a case on it! And the camera, well when people say it's probably the best camera on a cell phone these days, they aren't exaggerating.
What I don't like, Sense. Just not a fan of the UI. I actually like Sense in things like contacts/dialer/messaging, but aside from that, I don't want it. Went back to Launcher Pro for now. Waiting to unlock/root/ROM and maybe de-Sense this thing.
