Another vote for the CM Barely There here - been using on for a month or so and am very happy with it. Hardly adds any bulk to the phone but protects the back and corners against minor knocks - I don't worry about what surface I'm putting the phone down on now in case the back get scratched 
Also have a Nexus One neoprene slip case which I put the phone in (including the Barely There) when I want a bit of added protection
