I have a case on it it now but i do get the itch to go naykee sometimes. I bought the sleeve for the nexus one, that way i can take it out and have it in its full glory but still tuck it back in when not in use. I always have a screen protect but I have been using the case because i fear putting the backside down on the lens.
Exactly why I have a case on mine. I don't too scratch that beautiful camera lens and ruin all the pictures I take
