There's an awful lot of user error involved for someone to say the camera just "sucks". The camera is better than the iPhone 4 camera and people raved about that thing. I have had the Nexus One, Droid Incredible, Droid X, Thunderbolt, Droid X2, Droid Bionic, Droid Razr, Rezound, and the Galaxy Nexus so far. The Galaxy Nexus takes much better(not slightly better, much better) photos than all of them but the Rezound.
People need to learn how to take pictures; there is an understanding and skill involved in getting the perfect shot. There is much more to it than just holding the phone in a general direction and randomly hitting a button. The default settings may or may not be ideal for the lighting and movement conditions you are currently in. Default settings of different phones may not be good for the same types of pictures. Don't bother ever zooming in on a camera that uses digital zoom.
